Bitcoin(wallets) online vs offline

When you download a wallet and purchase bitcoin, does that bitcoin actually reside inside your wallet on your device? Or is the actual value stay online from where you purchase it from? The reason I'm asking is because of what happened with Gox and what is happening with Cryptsy. It just seems leaving your coins with an online vendor is just a huge gamble and not worth the chance of losing them.

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Unit Symbol Value Info
bitcoin BTC 1 bitcoin one bitcoin is equal to 100 million satoshis
millibitcoin mBTC 1,000 per bitcoin used as default unit in recent Electrum wallet releases
bit bit 1,000,000 per bitcoin colloquial "slang" term for microbitcoin (μBTC)
satoshi sat 100,000,000 per bitcoin smallest unit in bitcoin, named after the inventor

Everyday info sec, hardcore info sec, and DNMs

Edit: Currently writing a new version of this, dont know when it will be done.
Edit: Since first post I have updated a few sections with additional information.
I recommend reading it all even if it is very long, I might have placed some relevant info in different sections while thinking about what else needed to be added, plenty of steps remains mostly the same except when I comment directly on it. It is not necessary to do 100% security all the time, unless you absolutely need it, combining some high and some lower security ideas for a balance of security and convenience is useful.
I will base this mostly on Windows, Linux users probably know this, and I have no idea how apple machines work (tho many things in here are still relevant for other operating systems, as they are just general tips)
Disclaimer: There are certainly other steps that can make you more anonymous or safer, however I think for most people this will surfice. Any software I recommend should be independently verified for security, and examples of software are not to be taken as endorsements. I simply use examples and give recommendations when I believe it necessary, or helpful.
I will not really differentiate between anonymity and security, they are often the same thing. As such the word security can mean either more anonymous, less vulnerable, or both.
--------
Everyday Simple Info Sec:
-There could be a hidden administrator user on your PC, make sure to change its password
(Snapchat msgs, reddit dms, discord msgs, are just a few examples of msgs that are never encrypted)
-Any info even send in encrypted msgs (and obviously non encrypted) should still be kept with possible deniability, don't say "I'm gonna do MDMA", say "I'm going out with molly."
-DO NOT STORE ANY PASSWORDS ON GOOGLE, IF GOOGLE LOGIN IS AUTHENTICATED IT WILL AUTFILL ALL PASSWORDS IT HAS SAVED (same with other similar services) (This means if you are logged in to chrome and someone has access to your machine, they can auto fill passwords without entering a single password)
-use a rememberable passphrase, especially for your master key ring aka password manager A long sentence that is memorable makes an okay password (decent example,: "I met my wife at Little Ceasers for the first time on 07/09/20" better even if it's just something you know, if its impersonal, and if you can add special characters or numbers that you won't forget) (A better example for a passphrase is: "There is 0nly 0ne letter that d0esn’t appear in any U.S. state nameQ")
-Purge your internet activity frequently, there's a reason why I only have one post, and a few comments appearing in my account, but thousands of kama. Exposing information needlessly is not good.
-Never post private information publicly, and if you do, do it vaguely as possible. (Example: Not "I'm 15", say "I'm a teenager") Do not post any vital information ever, no birthdays, mother's maiden name, age, or anything you have ever seen in a security question. Never post your current activities while they are ongoing. You going on a vacation? Don't announce it to the world, taking picture there? Post them when you are home.
-Rethink how you do security questions. Many answers to security questions can be found in your internet history. One could use the first word of the security question as an answer, or a different sceme that will mean you always remember it. (Security question need to go, the amount of personal info an average person puts on the internet makes it easy to attack anything using security question)
-------_
High level crimimal information security:
The motto here is, "All the Security, All the Time" As one fuck up can end with you leaving a lick of traceability, and you could be fucked.
Pre Note: All of your software should always be up to date. Also even perfect info sec does not guarantee you are completely safe, a new zero day (exploit) can still fuck you, but good info security makes you significantly safer, by eliminating as many attacks as possible.
-Get a new device (or make a already owned device seem like you never owned it, do this only if you know how to, there's a lot of stuff that goes into that, like changing your mac adress etc) buy with cash, and your face covered, preferably far away from where you live. (Do I need to specify to not bring your phone or anything else that tracks your location to anywhere you want to go anonymously?) (Be aware that even hardware can have vulnerabilities, many cpus have known vulnerabilities, I can't list them all, do some research before buying)
-If you know how to use Tails (A linux distro designed for Info sec) use that, preferably on a USB. (Or learn how to use tails, its better, but complicated) Otherwise a clean copy of windows (make sure its not in any way associated with you) can do the job too, tho not as well. (Using a VM might give extra security, since VMs usually erase all data and RAM they were using on shutdown)
-Get a non tracking VPN, Enable the kill switch (a setting that disables all traffic that doesn't go through the VPN) (change your firewall settings to only allow the traffic from the VPN, windows guide (Change settings so only traffic from the tor application is send) Edit: (Due to complaints: do not use vpn over tor, use tor over vpn. tor over vpn has no notable downside, if the VPN logs it makes no difference, your ISP will always log anyways, and vpns remove other attack vectors and also provide backup security should tor fail. Again even if the VPN tracks you only change the people doing the tracking, but now you are further removed making it more anonymous and also with less vulnerabilities)
-rember privacy settings, cookie cleaner, and antivirus, password (There could be a hidden administrator user on your PC, make sure to change its password)
-Always use the device on a non admin account
-Ideally use this device only on networks that are not connected with you. Such as public networks (try to never use the same public networks twice, move around) (a home network should be fine now, as it should never be exposed, but more security is always better) (Its just a conveniences vs security trade)
-Never use accounts that have been exposed to lower security on higher security machines
-your browser is now TOR (or your preferred security focused browser, if you dont plan on using onion ) Make sure you get the standalone version of tor not the addon build (the standalone is safer, because there are less settings and options to tweak)
-Change your tor settings, to safest mode, enable a bridge (to my knowledge there's no difference in security between the build in bridges in tor), enable automatic updates, set duckduckgo onion as your primary browser. Set dark.fail onion page as your home page. (Or your preferred privacy search engine and onion directory)
-------_
How to use dark net markets (DNMs)
If you finished your High Security setup, we can dive right in. Otherwise go do that. This is where all that is essential.
Quick info on Tor, and onion sites. There is no search engine. It's all based of directories and addresses you are given by others. Tor will likely not be very quick, it has to pass through multiple networks to get to the destination. DNMs sometimes exit scam, an exit scam is when a market shuts down completely and takes all the money, this is a risk when using DNMs, it's not too common but happens maybe 0-4 times a year. The admins of thoese servers need to get out at some point, before they get jailed, so they exit the game, and scam everyone out of their money.
-A very useful onion directory is dark.fail it has a lot of links, for all kinds of stuff. News, email, DNMs, Psychonautwiki (harm reduction website), forums etc. (Other directories also exist)
-Pick a market, preferably one that handles secure connection server side instead of requiring you to establish the secure connection. Then create an account. Your account once created should include an entry box in your profile for a pgp key, post your PUBLIC key in there. (Verify the link is not a scam, most markets should provide a pgp signature)
-Next is currency setup. All major cryptocurrency exchangers can be used, I can recommend coin base but there could be better ones out there. Unless you find a small non U.S., exchange, they will always ask for your identity. So unless you can find a trustworthy exchange that doesn't ID, you will need to give it to them. (Side note, all major crypto exchangers report to the IRS, if the IRS asks you if you bought cryptocurrency and you bought while having IDed yourself SAY YES, DO NOT COMMIT TAX FRAUD WHEN THEY KNOW YOU DID)
-Transfer (monero you can send directly, btc you should scramble) to your wallet. There are two options a cold wallet (physical) or a software wallet. Software wallets usually dont cost anything so I recommend them, even if often less safe. Electrum is easy to use, and pretty safe. You can also do your own research and find a wallet that fits your needs.
-now you are ready to buy, only buy using escrow (it means the money is held by the market as a middle man until the product is delivered, they will also handle any issues like wrong quantity, cuts, etc), judge the reviews for a product, and if available look at the history of the vendor, until you find a product from a vendor you trust. (I recommend to buy within your country as much as possible, so it doesn't go through customs, it's very rare that something is found, but it can happen)
-now you get to buy, depending on market, you either have cryptocurrency stored in their wallets (not recommend, you will lose it in an exit scam) or you can send it every order. When you send your delivery adress (or the one you want it to go to) encrypt the adress using the sellers public key. Make sure the adress is correct.
-wait for the product, make sure to extend the escrow until the product arrives, if you can't extend it anymore dispute the order, and a moderator will step in
-test the product, use it, and leave a review. PLEASE LEAVE A REVIEW, DNMs only work because of reviews.
Edit: Didn't imagine I would write over 15000 words. Oh well, it was fun. Hope it helps, if you have any questions feel free to ask.
No idea how long this will stay up, I might purge it in 7 days, or never.

Common sites with HIGHEST payout and STABLE income << 04/10/2020 >>

This is a long post, but please try to read it all and select the most suitable one for you. When you see any sites with good payout and good potential, feel free to create a post. Also when you know site that is scam, please create a post to alert everyone as soon as possible.

There're 4 main and common types of task you will encounter when using beermoney sites. You can use all the sites or just pick the most suitable type and site to work with. Using more than one site is recommended, as the number of tasks on one site is not high enough, and the tasks will not appear continuously.

I. MICRO-TASK (or Crowdsourcing task)

The task is vary from article assessment, information collection, search-query classification/answer relevance, taking or collecting photo/video, to object identification,... The number of tasks will increase as you complete tasks.
Pros:
- The number of tasks is higher and more stable than other type of beermoney.
- The payout is appropriate to your time and effort. You can even make stable income with them.
Cons:
- Sometime you will need to pass the training test to access the task.
- Your work may not be accepted if it does not meet the guideline.
- It can be a little hard in the beginning, there're also not many tasks for you, but BE PATIENT, because they haven't been able to fully assess your ability yet.
1-Toloka Yandex:
This is one of my favorite micro task sites, and is the first on the list when I make beermoney site suggestion.
The tasks are mainly in English and Russian. They also have task in your mother language too, depend on your setting and location. Don't worry about the language, as you can easily have it to be translated with google translate extension or any translation site and the task is easy enough to understand.
The minimum withdrawal is $0.02 if you request to withdrawal once a week, and it will be $1 if more than once a week. You can withdraw the money to PayPal, Payoneer, Skrill or papara. But to be able to withdraw with PayPal, you will need a verified PayPal account.
Here are registration links: ref-link and no-ref
2-Clickworker:
One of the most popular micro task sites, you can find many recommendations and good reputation about them. But to make the most if it, you will need to unlock UHRS, as describe here.
You definitely shouldn't miss Clickworker and UHRS. Their payout rate is higher than Toloka, but be careful that you'll be considered as spam if you complete the task too fast. Depend on your location and language, you can earn a great amount of money here, the highest I've earned in 1 day is $35.
You can receive payment to PayPal account with the minimum of €5. You can choose other payment methods too, like SEPA transfers and Transferwise.
No need to say anymore, here are the links: ref-link and no-ref
3-Remotasks
You will need to take part in training (which is quite hard and time-consuming) and pass the test to be able to access a large number of tasks here. The tasks are categorization, text highlighting, image annotation, semantic segmentation,... and well-known Lidar Annotation and Segmentation.
Here are registration links: ref-link and no-ref

NOTE FOR MICRO-TASK:
  1. It's highly recommended to use all those sites, and maybe other sites if you want, because the tasks are not shown continuously.
  2. Make sure to fully understand the guideline, as you will not be credited if you work fails to meet the requirement, which will waste your time and effort.
  3. If you find any task with really low credit but require a lot of time and effort, don't do it. If the requester still be able to find worker, they will always offer that price. It's not worth your time, just going to other tasks or going to other sites to see if there're any available tasks for you.

II. OFFER WALL TASK

Another way to earn beermoney online is to complete Offer wall tasks. You will be asked to installing app on your smartphone, signing up, playing game and reaching determined level, or watching video,.... Doing survey can also be listed here, but it will be shown in separate section.
There're many offer walls for you to choose, with different payout level. Usually each beermoney site will list many offer walls, one offer can appear in more than one site/wall, so make sure to surf around and compare the credit to find the best and highest payout wall/site for that offer.
Pros:
- Easy to do
- Can complete offer many times if you have different kinds of phone (mostly Android and iOS), or using another phone as the tasks are listed on many different offer walls.
- Can earn money while playing and relaxing, as mostly the offered apps are games. Some apps only requires you to install and open, make it really quick to have some beermoney.
Cons:
- The payout is not very high. Especially when that offer is going through many walls and sites to reach you.
- Some offer take much time to complete.
- The number of offers is not high enough to do daily.
1-RewardXP
RewardXP has surpassed GG2U to become the highest payout site. They have leveling system, the higher level you reach, the more offer walls you can access and the more benefit you can get.
With the minimum of $5, they provide a variety of withdrawal methods for you to choose, like PayPal, Amazon, Steam,...
You definitely should try this site. Here are your registration links: ref-link and no-ref. Registration with referral link, you will be given a 5000XP (~$0.5) bonus.
2-GG2U:
This is also my favorite site. Their paying rate is one of the highest in the market (if you find any other site which is higher, feel free to suggest :D THE HIGHEST ONE NOW is RewardXP, see above). Aside from installing and registering app, they also have many survey walls for you.
The most attractive part is that they will give you $1 bonus right after signing up, and after 5 withdrawal requests, you will have a chance to earn up to $7 bonus. With bonus, it's hard to say which is better, RewardXP or GG2U.
You can withdraw money to your PayPal account or Coinbase (crypto wallet), with the minimum of $7.
Here are your links: ref-link and no-ref
3-Cointiply
One of the most popular sites, with great community.
They will pay you with cryptocurrency like Bitcoin or Doge. You will have many chances to earn coins, by doing offer walls task, rolling the faucet every 1 hour, testing your luck with multiplier or by activating in their really crowded chat room.
You can also earn some coins by clicking Paid-to-click ads. Most of the time, those ads are from Cointiply user with their referral link embedded, so if you register sites when viewing those ads, they will earn some commission. You can try this strategy too :D
With their mobile app, it will be much easier to do mobile offers. Make sure to check your email and mobile app to get the user-limited Promotion Codes regularly.
Registration links: ref-link and no-ref
4-Swagbucks
Sometime you can earn money by spending less. Swagbucks offers a big number of sites where you can receive cash back when you shop online. If you shop online a lot, it's worth to take a look
Here are registration link for shopping: ref-link-shopping and no-ref-shopping
Beside the cash back program, Swagbucks also provides offer wall, however the paying rate is not as high as site 1 and 2 above. Anyway, if you want to try, here're your registration links: ref-link and no-ref
5-EarnCrypto
If you're into doing offer walls task and earning crypto currency, try this site too.
Their paying rate is quite lower than above sites, but they have Data entry task, which is daily, for you to earn some coins. By ranking high on their daily leader board, you will be rewarded with a great amount of coins (can even be higher than your earning from doing the data entry task itself :D).
There are many different kinds of crypto currency for you to select.
Just take a look if you have time: ref-link and no-ref
NOTE FOR OFFER WALL TASK:
  1. Every offer wall has a place to track your activity history, like what offer you clicked, what offer you completed and did you receive credit or not. Every time you're about to do an offer, after entering that offer (usually when you click an offer, a small panel about what offer is appears, there will be a button name 'continue' or 'go to offer', after you click that button, you're entering the offer), make sure that offer appears in your history tab of that offer wall. This will enable you to request support in case you complete the offer and have not received credit yet. If it does not appear in the history list, you will not be credited for that offer, so try to click it again.
  2. To find the history tab, after entering offer wall, you will need to find a button named 'My coin', 'My history', 'Support', or button with question mark,... That button should be easy to be found.
  3. Try to surf around to find the offer wall and site having the highest paying rate for the offer, as the same offer will appear in many offer walls and sites.
  4. When you're about to start to do an offer of installing app (especially game), try to read the comment in appstore/playstore to see whether the offer's requirements can be easily to fulfill or not. For example, the requirements are: 1. install game, 2. open it, 3. reach level 30; and you find some comment about cannot reach level 25, or it takes months to reach level 29, then skip that offer, it's not worth the try.

III. PAY TO SEARCH

You can earn nearly passive income from this type of task. They will give you some query, you will search with that query, entering determined site, leaving that site opened for couple of minutes.
Pros:
- It's super easy to do.
- While leaving the site open, you can do any other thing you want, like doing some micro-tasks.
- The paying rate is quite good, especially when you will not need to do much.
Cons:
- The number of queries is not very high.
1-SerpClix
In order to receive more queries to search, make sure to leave the site open and allow the notification.
Even though SerpClix recommends you to click on the page, don't do that, just using scrollbar. SerpClix will automatically navigate to sub page of that page. Another suggestion here is to install adblock extension, because SerpClix will ban you if you click on any ads on the page, so blocking them before hand is a good move.
Here your registration links: ref-link and no-ref

IV. SURVEY

Probably all offer walls have some kind of surveys there, some surveys are only available through offer walls, some have their own sites. By using their own sites will not guarantee that you will have higher payout though.
Make sure to be honest when doing survey, despite the fact that you will sometime be disqualified from the survey. There's many reasons why you are disqualified, like because your job is not suitable, your demography is not their target, your answer is not persistent,...
BE CAREFUL, they will keep track of you, even if you clear your cookie, so being dishonest can lead you to be banned from their sites. Again, BE HONEST, and there will be suitable surveys for you.
There will be two types of survey for you: the first one is filling form and selecting answer from their suggestion, the second one is to talk with them directly or via Video call apps. The second one has much much higher earning but the requirement is also higher too.
Pros:
- Easy to do, just being honest
- High payout, especially with the second type of survey.
- Some survey only need 5 minutes to complete with good payout.
Cons:
- Some survey can take about 30 minutes to complete, so make sure that you have enough free time.
- You will be disqualified if your information is not suitable to their survey's target. BUT ALWAYS BE HONEST.
1-SurveyTime
One of the best sites out there, my favorite one. They will instantly send you $1 or $0.5 (depend on survey) to your PayPal or Coinbase account when you complete the survey, so no minimum required to withdrawal. The survey you will do here is the first type, filling in the form and selecting answer.
You can register with SurveyTime through some offer walls, as they will give you some more coins when you complete the survey, but make sure to check their's conditions.
Make sure to turn on Browser notification and Email notification so that you don't miss any survey.
Registration links: no-ref
2-Respondent
You will need a microphone and/or webcam (built-in or external) as the survey in Respondent is conducted via video calls, phone calls, in-person discussions. Of course, you will receive a huge credit for doing survey here, from $5 up-to $1000. This's a great deal, one successful survey can get you more credit than doing hundreds of micro-tasks. Don't miss this site.
They will recommend suitable survey for you, but if you want to view all available survey, make sure to uncheck the 'Recommended' option in Filter panel.
Here're your registration links: ref-link and no-ref
NOTE FOR SURVEY TASK:
  1. sometime, they will provide the must-select answer in the question to test if your attention. Make sure to read the question carefully. For example, the question is "Do you agree that 1 + 1 = 2? Select option [I do not agree] in the answer", if you select [I agree], you fail.
  2. BE CAREFUL - BE HONEST
  3. When you're doing the first type survey (filling form, selecting answer), be careful not to install any app, or download any thing, or upload your social data file when asked. In that case, just contact survey site support and report it.
  4. It's better to use many different survey sites to maximum the number of surveys you receive.

Last word, BE PATIENT - earning online can be a little hard in the beginning.

Some Basics Of Bitcoin

For someone not familiar with Bitcoin, the first question that comes to mind is, "What is Bitcoin?" And another common question that is often asked relates to the Bitcoin price. It started out a under 10 cents per Bitcoin upon its introduction in early 2009. It has risen steadily since and has hovered around $4000 per Bitcoin recently. So regarding Bitcoin value or the Bitcoin rate this is a most remarkable appreciation of value and has created many, many millionaires over the last eight years.
The Bitcoin market is worldwide and the citizens of China and Japan have been particularly active in its purchase along with other Asian countries. However, recently in Bitcoin news the Chinese government has tried to suppress its activity in that country. That action drove the value of Bitcoin down for a short time but it soon surged back and is now close to its previous value.
The Bitcoin history chart is very interesting. Its creator was an anonymous group of brilliant mathematicians (using the pseudonym Satoski Nakamoto) who designed it in 2008 to be "virtual gold" and released the first Bitcoin software in early 2009 during the height of the USA economic crisis. They knew that to have lasting value, it like gold had to have a finite supply. So in creating it they capped the supply at 21 million Bitcoin.
Bitcoin mining refers to the process by which new Bitcoin is created. With conventional currency, government decides when and where to print and distribute it. With Bitcoin, "miners" use special software to solve complex mathematical problems and are issued a certain number of Bitcoin in return.
A question that then arises is, is Bitcoin mining worth it. The answer is NO for the average person. It takes very sophisticated knowledge and a powerful computer system and this combination of factors makes it unattainable for the masses. This applies even more to bitcoin mining 2017 than in past years.
Many wonder, who accepts Bitcoin? This question gets asked in various ways, what are stores that accept bitcoin, what are websites that accept bitcoins, what are some retailers that accept bitcoin, what are some places that accept bitcoin and where can I spend bitcoin.
More and more companies are beginning to see the value of accepting cryptocurrencies as a valid payment option. Some major companies that do are DISH network, Microsoft, Expedia, Shopify stores, Newegg, Payza, 2Pay4You, and others.Two major holdouts at this time are Walmart and Amazon.
Ethereum is the strongest rival to Bitcoin in the cryptocurrency market and many wonder at the question of Bitcoin vs Ethereum. Ethereum was created in mid-2015 and has gained some popularity but still ranks far behind Bitcoin in usage, acceptance and value.
A question that often comes up often relates to Bitcoin scam. This author has a friend who made a purchase from a company that promised 1-2% growth per day. The company website listed no contact information and after a couple months the website simply vanished one day and my friend lost all the money he had invested which was several thousand dollars.
One has to know how to buy Bitcoins, how to purchase Bitcoin or how to buy Bitcoin with credit card in order to get started. Coinbase is a very popular site to do this. Their fee is 3.75% and the buying limit is $10,000 per day. This would probably be the easiest way to buy bitcoins.
Others would like to buy Bitcoin with debit card. Coinbase also provides this service and has clear step by step instructions on how to proceed with either your debit or credit card.
There are those who would like to buy Bitcoin instantly. This can be done at Paxful, Inc. and can be done through W. Union or any credit/debit card.
Other common questions that come up are what is the best way to buy Bitcoins, the best way to get bitcoins or where to buy bitcoins online. The easiest way is probably to purchase it through a digital asset exchange like the previously mentioned Coinbase. Opening an account with them is painless and once you link your bank account with them you can buy and sell Bitcoin quite easily. This is quite likely also the best place to buy Bitcoins.
One must know what a Bitcoin wallet is and how to use it. It is simply the Bitcoin equivalent of a bank account. It allows you to receive Bitcoins, store them and send them to others. What it does is store a collection of Bitcoin privacy keys. Typically it is encrypted with a password or otherwise protected from unauthorized access.
There are several types of digital wallets to choose from. A web wallet allows you to send, receive and store Bitcoin though your web browser. Another type is a desktop wallet and here the wallet software is stored directly on your computer. There are also mobile wallets which are designed for use by a mobile device.
A question that occasionally comes up is that of Bitcoin stock or how to buy Bitcoin stock. By far the most common way to proceed in this area is to buy Bitcoin directly and not its stock.
There is one entity called Bitcoin Investment trust which is an investment fund that is designed to track the market flow of Bitcoin. Some analysts however are calling this a risky way to become involved in this marketplace.
The Bitcoin exchange rate USD is a closely watched benchmark both on a daily basis and long term over the last 8 years since its introduction to the world's financial marketplace. A popular company to receive the most current rate in Bitcoin valuation is XE. They show Bitcoin to USD valuation and also the complete Bitcoin price chart, the Bitcoin value chart and the Bitcoin to USD chart. If you ask, "How much is one Bitcoin?" you will always know from their continuously updated charts.
Similar questions that come up in this area relate to the bitcoin rate history, the bitcoin price chart live, the bitcoin to dollar exchange rate, the bitcoin dollar chart and the bitcoin 5 year chart. The previously mentioned website, xe, is also a good source for answers to these questions.
Regarding Bitcoin cash, ie. to get USD from selling Bitcoin, Bitwol is one company that enables you to do this. WikiHow is another company that will take you through this process.

How to Buy Bitcoin 2

Bitcoin: All You Need to Know

Bitcoin is popular across due to its robust technologies as well as substantial market value. It has the potential to ensure huge and more profits compared to other currencies. As it controls the market, other currencies get affected when Bitcoin experiences any price fluctuations.
Bitcoin is a preferred choice for most traders and investors in the currency industry. The reliability makes it a perfect choice for online and offline stores to use it as a payment method.
Many show interest in Bitcoin. However, common people have a limited idea about it. They do not know where to buy it and how to use it while buying a commodity. In this article, we are going to answer all your queries related to Bitcoin. Keep reading to know how to be benefited from Bitcoin.

How to Buy Bitcoin

1. Start with a Wallet

You will need a wallet to store Bitcoin. You can link your wallet with leather wallets that you use for fiat currency. It can also house Bitcoin.
When it comes to wallets, you will find many options to choose from. Some of them are introduced by popular developers and other leading names in the industry. You can operate a wallet offline and online. You will have to research on available wallets to choose the best one to store your Bitcoin.

Things to Consider While Choosing A Wallet


2. Find A Reliable Bitcoin Trader

Choose a secure and easy-to-use wallet and then look for a trustworthy and reputed Bitcoin trader. While choosing a trader, your focus should be on the legit and trusted trader to make your first purchase safe and hassle-free.
You can consider a peer-to-peer platform or online exchanger. These two are different and work in specific and different ways. You need to open an account on the platform you find worth investing in. Here are a few things you need to go through while opening an account on any of the above two platforms:

After going through all these steps, you can have your account. Next, you will have to choose a payment method that you will use for the transactions.

Peer-to-Peer Vs Exchange Platforms

With exchanges, you can sell or buy Bitcoins on market trends. The exchange platform is considered easy for beginners. It will pair you with sellers mostly one with the lowest offer. You can pair with multiple sellers or one seller. You will have the freedom to choose the best seller depending on availability.
The peer-to-peer platform will not allow users to trade or exchange Bitcoin. The sellers and buyers will come together on the site to plan trades. You can consider trading both offline and online.

How to Choose the Payment Mode

You can expect different types of payment options regardless of the platform you prefer. Peer-to-peer and exchange platforms support flexible payment methods. You can use your credit or debit card for deposits. Some other options are e-wallets and PayPal. You can use any of them to purchase Bitcoin.
While choosing any of these two platforms, you will have to ensure that they offer many deposit options. By doing so, you can find the most suitable deposit option. All the payment options are not the same. The speed of the delivery and time will vary depending on the deposit option. So, make sure that you are choosing an option that ensures fast withdrawal and deposits.
A few platforms are known for offering direct wire transfer. The wire transfer will ensure fast deposits and withdrawals. You can choose any option depending on your convenience. If you are using your e-wallet or card for deposits, you should consider other payment modes instead of direct wire transfer.

Buy & Store Bitcoin

You need to place an order on exchange platforms to buy Bitcoin. Once you place the order, it will move into booking. The booked order will be paired with the involved sellers to find the most affordable rate. The Bitcoin will be reflected in your account immediately after completing the transaction.
As Bitcoin will show on your exchange account, you will have to transfer it from the platform into your wallet that you have created much before.

Plan the Next Step

The crypto industry is volatile. So, you will have to act smart to make money from the volatile market condition. The price might drop and rise suddenly.
Before planning any investment, you should understand the market condition. You should observe the market and research the trades before purchasing Bitcoin. If you find the market condition unfavorable, you can store the Bitcoin and use it when the market condition indicates a profit. However, it is suggested to use the Bitcoin immediately to complete a transaction or place a trade.

Conclusion

In the current condition, a few crypto ATMs allow traders to trade their fiat for Bitcoin directly. But these ATMs are limited and not available in all the locations. So, you will have to consider other reliable methods to avoid fraud. Enhanced security is a must in the currency trade.

Don't blindly follow a narrative, its bad for you and its bad for crypto in general

I mostly lurk around here but I see a pattern repeating over and over again here and in multiple communities so I have to post. I'm just posting this here because I appreciate the fact that this sub is a place of free speech and maybe something productive can come out from this post, while bitcoin is just fucking censorship, memes and moon/lambo posts. If you don't agree, write in the comments why, instead of downvoting. You don't have to upvote either, but when you downvote you are killing the opportunity to have discussion. If you downvote or comment that I'm wrong without providing any counterpoints you are no better than the BTC maxis you despise.
In various communities I see a narrative being used to bring people in and making them follow something without thinking for themselves. In crypto I see this mostly in BTC vs BCH tribalistic arguments:
- BTC community: "Everything that is not BTC is shitcoin." or more recently as stated by adam on twitter, "Everything that is not BTC is a ponzi scheme, even ETH.", "what is ETH supply?", and even that they are doing this for "altruistic" reasons, to "protect" the newcomers. Very convenient for them that they are protecting the newcomers by having them buy their bags
- BCH community: "BTC maxis are dumb", "just increase block size and you will have truly p2p electronic cash", "It is just that simple, there are no trade offs", "if you don't agree with me you are a BTC maxi", "BCH is satoshi's vision for p2p electronic cash"
It is not exclusive to crypto but also politics, and you see this over and over again on twitter and on reddit.
My point is, that narratives are created so people don't have to think, they just choose a narrative that is easy to follow and makes sense for them, and stick with it. And people keep repeating these narratives to bring other people in, maybe by ignorance, because they truly believe it without questioning, or maybe by self interest, because they want to shill you their bags.
Because this is BCH community, and because bitcoin is censored, so I can't post there about the problems in the BTC narrative (some of which are IMO correctly identified by BCH community), I will stick with the narrative I see in the BCH community.
The culprit of this post was firstly this post by user u/scotty321 "The BTC Paradox: “A 1 MB blocksize enables poor people to run their own node!” “Okay, then what?” “Poor people won’t be able to use the network!”". You will see many posts of this kind being made by u/Egon_1 also. Then you have also this comment in that thread by u/fuck_____________1 saying that people that want to run their own nodes are retarded and that there is no reason to want to do that. "Just trust block explorer websites". And the post and comment were highly upvoted. Really? You really think that there is no problem in having just a few nodes on the network? And that the only thing that secures the network are miners?
As stated by user u/co1nsurf3r in that thread:
While I don't think that everybody needs to run a node, a full node does publish blocks it considers valid to other nodes. This does not amount to much if you only consider a single node in the network, but many "honest" full nodes in the network will reduce the probability of a valid block being withheld from the network by a collusion of "hostile" node operators.
But surely this will not get attention here, and will be downvoted by those people that promote the narrative that there is no trade off in increasing the blocksize and the people that don't see it are retarded or are btc maxis.
The only narrative I stick to and have been for many years now is that cryptocurrency takes power from the government and gives power to the individual, so you are not restricted to your economy as you can participate in the global economy. There is also the narrative of banking the bankless, which I hope will come true, but it is not a use case we are seeing right now.
Some people would argue that removing power from gov's is a bad thing, but you can't deny the fact that gov's can't control crypto (at least we would want them not to).
But, if you really want the individuals to remain in control of their money and transact with anyone in the world, the network needs to be very resistant to any kind of attacks. How can you have p2p electronic cash if your network just has a handful couple of nodes and the chinese gov can locate them and just block communication to them? I'm not saying that this is BCH case, I'm just refuting the fact that there is no value in running your own node. If you are relying on block explorers, the gov can just block the communication to the block explorer websites. Then what? Who will you trust to get chain information? The nodes needs to be decentralized so if you take one node down, many more can appear so it is hard to censor and you don't have few points of failure.
Right now BTC is focusing on that use case of being difficult to censor. But with that comes the problem that is very expensive to transact on the network, which breaks the purpose of anyone being able to participate. Obviously I do think that is also a major problem, and lightning network is awful right now and probably still years away of being usable, if it ever will. The best solution is up for debate, but thinking that you just have to increase the blocksize and there is no trade off is just naive or misleading. BCH is doing a good thing in trying to come with a solution that is inclusive and promotes cheap and fast transactions, but also don't forget centralization is a major concern and nothing to just shrug off.
Saying that "a 1 MB blocksize enables poor people to run their own" and that because of that "Poor people won’t be able to use the network" is a misrepresentation designed to promote a narrative. Because 1MB is not to allow "poor" people to run their node, it is to facilitate as many people to run a node to promote decentralization and avoid censorship.
Also an elephant in the room that you will not see being discussed in either BTC or BCH communities is that mining pools are heavily centralized. And I'm not talking about miners being mostly in china, but also that big pools control a lot of hashing power both in BTC and BCH, and that is terrible for the purpose of crypto.
Other projects are trying to solve that. Will they be successful? I don't know, I hope so, because I don't buy into any narrative. There are many challenges and I want to see crypto succeed as a whole. As always guys, DYOR and always question if you are not blindly following a narrative. I'm sure I will be called BTC maxi but maybe some people will find value in this. Don't trust guys that are always posting silly "gocha's" against the other "tribe".
EDIT: User u/ShadowOfHarbringer has pointed me to some threads that this has been discussed in the past and I will just put my take on them here for visibility, as I will be using this thread as a reference in future discussions I engage:
When there was only 2 nodes in the network, adding a third node increased redundancy and resiliency of the network as a whole in a significant way. When there is thousands of nodes in the network, adding yet another node only marginally increase the redundancy and resiliency of the network. So the question then becomes a matter of personal judgement of how much that added redundancy and resiliency is worth. For the absolutist, it is absolutely worth it and everyone on this planet should do their part.
What is the magical number of nodes that makes it counterproductive to add new nodes? Did he do any math? Does BCH achieve this holy grail safe number of nodes? Guess what, nobody knows at what number of nodes is starts to be marginally irrelevant to add new nodes. Even BTC today could still not have enough nodes to be safe. If you can't know for sure that you are safe, it is better to try to be safer than sorry. Thousands of nodes is still not enough, as I said, it is much cheaper to run a full node as it is to mine. If it costs millions in hash power to do a 51% attack on the block generation it means nothing if it costs less than $10k to run more nodes than there are in total in the network and cause havoc and slowing people from using the network. Or using bot farms to DDoS the 1000s of nodes in the network. Not all attacks are monetarily motivated. When you have governments with billions of dollars at their disposal and something that could threat their power they could do anything they could to stop people from using it, and the cheapest it is to do so the better
You should run a full node if you're a big business with e.g. >$100k/month in volume, or if you run a service that requires high fraud resistance and validation certainty for payments sent your way (e.g. an exchange). For most other users of Bitcoin, there's no good reason to run a full node unless you reel like it.
Shouldn't individuals benefit from fraud resistance too? Why just businesses?
Personally, I think it's a good idea to make sure that people can easily run a full node because they feel like it, and that it's desirable to keep full node resource requirements reasonable for an enthusiast/hobbyist whenever possible. This might seem to be at odds with the concept of making a worldwide digital cash system in which all transactions are validated by everybody, but after having done the math and some of the code myself, I believe that we should be able to have our cake and eat it too.
This is recurrent argument, but also no math provided, "just trust me I did the math"
The biggest reason individuals may want to run their own node is to increase their privacy. SPV wallets rely on others (nodes or ElectronX servers) who may learn their addresses.
It is a reason and valid one but not the biggest reason
If you do it for fun and experimental it good. If you do it for extra privacy it's ok. If you do it to help the network don't. You are just slowing down miners and exchanges.
Yes it will slow down the network, but that shows how people just don't get the the trade off they are doing
I will just copy/paste what Satoshi Nakamoto said in his own words. "The current system where every user is a network node is not the intended configuration for large scale. That would be like every Usenet user runs their own NNTP server."
Another "it is all or nothing argument" and quoting satoshi to try and prove their point. Just because every user doesn't need to be also a full node doesn't mean that there aren't serious risks for having few nodes
For this to have any importance in practice, all of the miners, all of the exchanges, all of the explorers and all of the economic nodes should go rogue all at once. Collude to change consensus. If you have a node you can detect this. It doesn't do much, because such a scenario is impossible in practice.
Not true because as I said, you can DDoS the current nodes or run more malicious nodes than that there currently are, because is cheap to do so
Non-mining nodes don't contribute to adding data to the blockchain ledger, but they do play a part in propagating transactions that aren't yet in blocks (the mempool). Bitcoin client implementations can have different validations for transactions they see outside of blocks and transactions they see inside of blocks; this allows for "soft forks" to add new types of transactions without completely breaking older clients (while a transaction is in the mempool, a node receiving a transaction that's a new/unknown type could drop it as not a valid transaction (not propagate it to its peers), but if that same transaction ends up in a block and that node receives the block, they accept the block (and the transaction in it) as valid (and therefore don't get left behind on the blockchain and become a fork). The participation in the mempool is a sort of "herd immunity" protection for the network, and it was a key talking point for the "User Activated Soft Fork" (UASF) around the time the Segregated Witness feature was trying to be added in. If a certain percentage of nodes updated their software to not propagate certain types of transactions (or not communicate with certain types of nodes), then they can control what gets into a block (someone wanting to get that sort of transaction into a block would need to communicate directly to a mining node, or communicate only through nodes that weren't blocking that sort of transaction) if a certain threshold of nodes adheres to those same validation rules. It's less specific than the influence on the blockchain data that mining nodes have, but it's definitely not nothing.
The first reasonable comment in that thread but is deep down there with only 1 upvote
The addition of non-mining nodes does not add to the efficiency of the network, but actually takes away from it because of the latency issue.
That is true and is actually a trade off you are making, sacrificing security to have scalability
The addition of non-mining nodes has little to no effect on security, since you only need to destroy mining ones to take down the network
It is true that if you destroy mining nodes you take down the network from producing new blocks (temporarily), even if you have a lot of non mining nodes. But, it still better than if you take down the mining nodes who are also the only full nodes. If the miners are not the only full nodes, at least you still have full nodes with the blockchain data so new miners can download it and join. If all the miners are also the full nodes and you take them down, where will you get all the past blockchain data to start mining again? Just pray that the miners that were taken down come back online at some point in the future?
The real limiting factor is ISP's: Imagine a situation where one service provider defrauds 4000 different nodes. Did the excessive amount of nodes help at all, when they have all been defrauded by the same service provider? If there are only 30 ISP's in the world, how many nodes do we REALLY need?
You cant defraud if the connection is encrypted. Use TOR for example, it is hard for ISP's to know what you are doing.
Satoshi specifically said in the white paper that after a certain point, number of nodes needed plateaus, meaning after a certain point, adding more nodes is actually counterintuitive, which we also demonstrated. (the latency issue). So, we have adequately demonstrated why running non-mining nodes does not add additional value or security to the network.
Again, what is the number of nodes that makes it counterproductive? Did he do any math?
There's also the matter of economically significant nodes and the role they play in consensus. Sure, nobody cares about your average joe's "full node" where he is "keeping his own ledger to keep the miners honest", as it has no significance to the economy and the miners couldn't give a damn about it. However, if say some major exchanges got together to protest a miner activated fork, they would have some protest power against that fork because many people use their service. Of course, there still needs to be miners running on said "protest fork" to keep the chain running, but miners do follow the money and if they got caught mining a fork that none of the major exchanges were trading, they could be coaxed over to said "protest fork".
In consensus, what matters about nodes is only the number, economical power of the node doesn't mean nothing, the protocol doesn't see the net worth of the individual or organization running that node.
Running a full node that is not mining and not involved is spending or receiving payments is of very little use. It helps to make sure network traffic is broadcast, and is another copy of the blockchain, but that is all (and is probably not needed in a healthy coin with many other nodes)
He gets it right (broadcasting transaction and keeping a copy of the blockchain) but he dismisses the importance of it

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Staking in Compendia and how its approach differs from other (D)PoS networks

In this article, we'll be discussing staking and how it works in Compendia.
There are several misconceptions out there that arise due to the way staking is utilized across different networks. Compendia use a novel way of staking, by combining the way it locks funds to earn more coins in recent proof-of-stake (PoS) networks - with the aspect of vote power traditionally seen in delegated proof-of-stake (DPoS) networks.
Staking in (D)PoS networks vs. Compendia
Staking (commonly misspelt as 'stacking' or 'steaking') is the process of leveraging an acquired amount of coins/tokens from a certain blockchain to contribute to the network, by holding them in an address and using an (either online or offline) wallet client to earn revenue based on the amount of coins/tokens held.
PoS (proof-of-stake) networks
In traditional proof-of-stake networks such as Stratis or Cardano requires users to purchase a certain amount of coins, place those in an online wallet and letting the wallet client emulate a certain amount of computing power - which is in turn used to mine/forge new blocks to the blockchain. In more recent proof-of-stake networks such as Cosmos, users are required to lock their funds in an address - with a cooldown period added when wanting to unlock those funds. This way, coins are taken out of circulation rather than just being held (but still immediately spendable) as with Stratis/Cardano. In both situations, anyone can contribute to the network by staking and the more coins staked, the higher likelihood of mining/forging a new block and earning the block reward. You can earn individually from staking, or join a pool.
DPoS (delegated proof-of-stake) networks
In delegated proof-of-stake networks, such as ARK or EOS, there are only a set number of nodes (known as validators, block producers or delegates) that are allowed to forge new blocks. In ARK, there are 51 forging delegates and we will use this amount as an example. Contributors have to gain votes from other network participants, who pledge their account balance as votes, and once they have a total amount of votes that put them into the top 51, they will be able to forge blocks and earn rewards. The account balance of participants who vote for a forging validator remain unlocked and therefore it is possible to immediately spend funds held in an address. The amount of votes per address varies across different DPoS networks, but the principle is the same: one coin means one vote power. You can only earn individually if you are one of the top validators; otherwise, you have to vote and receive a portion of rewards from a forging validator.
Compendia
In Compendia, the above two methods are combined into a new dynamic: staking your BIND locks up your funds for a set period (3 - 6 - 12 months) as in proof-of-stake networks, but it does NOT grant the ability to earn. You will still need to vote for a sharing validator, like in delegated proof-of-stake networks. What does staking do then, if it does not let you earn on its own?
Staking your BIND for a set period applies a multiple (5x - 7.5x - 10x) to the voting power of your staked balance. This means that one staked BIND is no longer counted as one vote, but as 5 votes (or 7.5 votes, or 10 votes - depending on the lock period). This way it increases your potential earnings when you vote for a sharing validator. So, by pledging to lock your funds for a certain amount of time and thereby decreasing the circulating amount of BIND, you will be able to earn more with the same amount of coins than if you would not stake, and only vote.
When staking, your BIND will go through 5 different phases:
Securing the Network
DPoS delegates/validators secure the blockchain through forging blocks, and in the case of Compendia, there are 47 validators (rather than the 51 in ARK) and each active validator forges one block every 6 seconds. Therefore 47 new blocks are forged every 4.7 minutes (6 * 47 = 282 seconds = 4.7 minutes). In a similar way to proof-of-work networks such as Bitcoin, a block contains transactions and the validator that forges them receives a proportion of the transaction fee (described in the Fee Removal Model further below).
Supply Inflation
DPoS chains typically have fixed inflation based over several years, this is to help control the coin supply in circulation. Inflation comes from Delegate/Validators forging new blocks as described above. The effect of validators forging new blocks increases the supply by either ß3.9 per block (if ranked 6th to 47th), or ß4.84 per block (if ranked 1st to 5th).
The Compendia blockchain produces around ß1,753,200 - Per month
Block rewards are controlled through an annual milestone which is fixed in the current networks config. This can only be updated if the 47 validators reach consensus and accept the potential change.
The milestones for BIND are as follows:
Years Rewards (6-47) Rewards (Top 5) Average
1-3 3.9 4.84 4
4-6 1.95 2.42 2
7-9 0.975 1.21 1
Deflationary Effects
In general DPoS blockchains allow voters to vote, allocating their wallet weight to a specific delegate/validator and receiving rewards commensurate to weight. This helps control inflation as the coins are out of supply when being used to vote, but the coins are not locked for a fixed time, a voter can move some or all funds at any time.
What differentiates Compendia?
The key difference is that staked coins are locked for a fixed period, either 3, 6, or 12 months (as described above). The coins are effectively locked out of supply, by incentivising voters to lock their coins for the maximum period of 12 months. This helps offset the increase in supply through forging rewards.
At the time of writing, ß11,816,021 is currently locked into staking, given the current BIND supply (i.e nOS to BIND) ß112,894,676, around 10% of all BIND in circulation is locked out of supply for the staking periods highlighted earlier. With the current staked coins, it would take just over 6 months for inflation to offset the monthly forging reward increase.
Fee removal model.
Compendia also offer another deflationary measure through a sophisticated fee removal model.
The Fee Collection and Removal Model works as follows:
- 100% of collected fees up to the amount equal to the block reward in a block are permanently removed from circulation.
- 50% of any remaining collected fees are also removed from circulation.
- The other 50% is awarded to the forging validator.
This fee system helps with combating possible shifts in Vote Power going from voters towards validators during times of increased transaction activity on the network.
Summary
The Compendia Team has a clear understanding of the tokenomics of a blockchain, lessons have been learned from earlier DPoS implementations and new strategies have been deployed to ensure a fairer, more balanced approach to DPoS tokenomics.

Fastest and easiest way without a minimum purchase or high fees for customers to obtain NANO? (USA)

Hello Nano community,
Some of you may know me from /nanotrade or elsewhere, I generally am bullish on NANO and try to do my part to help spread adoption and awareness. I also run several e-commerce websites utilizing the open source Zen-Cart as my back end. Lately, and not so lately but in general, I have encountered issues with various payment processors (which actually led me to Nano in the first place, as well as a general interest in Cryptocurrency).
While there are solutions to dealing with the more stringent regulations enforced by payment processing companies, many of these require my customers to download third party apps or sign up for third party services. Not too dissimilar to how Paypal requests a user to be logged in before sending a payment in fact. Anyways, so while setting up my websites again today after losing another payment processor over the weekend, I have come to the decision, why not try and introduce my customer base to Nano and present it less so as a cryptocurrency, but more so as a digital decentralized payment solution? I have tried accepting cryptocurrencies before, however many of my customers, at least for my main e-commerce website are older and not so tech oriented. Just seeing that I accepted "Cryptocurrency" and "Bitcoin" as an option was enough to scare some of these people away. Ironically, I noticed more sales when I completely removed this payment option and all mentions of it from my website. Funny how that works.
Anyways, since I am in the middle of setting up additional payment methods, I figured now would be a good time to attempt the above with Nano, and offer a link on the "Pay with Nano" page during the check-out process for my customers to decide if they would like to try it out. My only concern, many of these people being older and technophobic, is that the process for obtaining the Nano they want to spend may be too much work and not something they would be interested in. Especially if it involves things like scanning IDs or providing more information than a simple credit or debit card number and a name. Ideally, this would be the only information they need to provide, with the ability to purchase any amount (most orders placed are between $25-$100), without paying an outrageous fee (which I will offer an incentive to cover for anyways I think). An instant transfer would also be a prerequisite. Something as fast as it takes to sign up for Cash App for example.
So, am I asking too much? Do such services exist yet in the US?
Quick rundown:
-Low fees
-No minimum or low minimum
-Non-invasive signup process
-No wait
Another thing worth mentioning, and hopefully this can provide the right people with an idea which I think could really help improve Nano adoption if implemented, was that I noticed some competitors of mine are accepting something called "PMC Coin", which is claimed to be a gold backed cryptocurrency. The gold bit is not important I do not think. What is impressive however, is that these vendors are able to provide this crypto as an option during the checkout process, and upon hitting submit, the customer is brought to the PMC Coin website, where they are presented with a form for purchasing this crypto. I have not tried going further than this, but the form contains all the required fields for a credit and debit purchase, as well as the price for the purchase being exactly what the price was for the requested items during the check-out on the forwarding website. It appears that upon purchase, the credit/debit card payment is sent to the PMC Coin sellers, and the PMC Coin in an equivalent amount is sent to the vendor. I assume the fees are offloaded onto the vendor at this point. While I have no interest in this asset in the slightest, I have to commend them on this solution, and I really hope we can see something like this emerge from the Nano community. It could be the killer app we have all been waiting for to spur adoption perhaps.
I will essentially be manually doing something like this for my customers, albeit with links and instructions, however as mentioned, the more streamlined the process is, the better. I am sure they will have an easy enough time with Natrium, and I am excited to introduce some new people into the space. But most of all I just want a simple ability to be able to keep my shop online without having to bow down to the banks and their petty requests as to what products should or should not be sold. None of us should have to deal with the Soup Nazi, be us merchants or consumers.
Thank you for your time and interest, and remember, stay bullish!
::edit::
Spreads I have found so-far:
CoinGate: 100 Nano = $114.76 vs. $97.44 USDT (Binance) [$17.32 fee] [$50 minimum] (Simplex)
Atomic Wallet: 100 Nano = $115 vs. $98.40 USDT (Binance) [$16.60 fee] [$50 minimum] (Simplex)
Crypto.com: Claims 3.5% fee, requires government photo ID, 2-3 day confirmation
Coinswitch.io: 100 Nano = $117 vs. $99.28 USDT (Binance) [$17.72 fee] [$63 minimum] (Simplex)
Coinify.com: 100 Nano = $119 vs. $114 USDT (Binance) [$5 fee] [$63 minimum] KYC is intensive but not too crazy. 2 Minute verification too. Definitely the best option so far. Only problem is the minimum purchase.
Going to try Binance.us next and the Brave browser, which I think uses Binance as a backend anyways.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

There's a video version that can be watched, and you can find out how to get the second two parts if you want on my website (video link on the page): https://cryptoramble.com/guide-on-privacy-coins/

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:
