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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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.

Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor

Trouble with signing / verifying bitcoin signed messages

Recently I've been having some trouble with trying to sign Legacy Bitcoin addresses messages and then verifying them with unrelated wallets. This has nothing to do with Segwit addresses and only related to original addresses. Specifically when signing a message with a legacy private Key address and then trying to verify it with the Bither wallet. Specifically what's happening is when I try to sign a message in mycelium and then verify the signature with bitter I get an error that the signature does not match even though I'm absolutely positive that I have properly sign the message with mycelium and that the message itself has no spaces are capitals or anything else that may throw off the signature. Does anyone else having issues with signatures from Bitcoin addresses? I feel as though this is a vital part of having true Financial autonomy over your own digital assets and that you are able to conclusively prove ownership of the addresses via signing messages with a private key where you have Bitcoin associated.

Trouble with bitcoin messages signing / verification

Up until fairly recently I've always been fairly comfortable signing messages from bitcoin addresses from legacy Bitcoin addresses and then verifying those signatures with other bitcoin wallets. Recently however I've started to be concerned over the inability to so consistently throughout the various wallet implementations. The most recent example I experienced was when I performed the following steps with the most recent versions of Mycelium and Bither on an android phone (both of which are recommended by bitcoin dot org) :
1) Selected a legacy Bitcoin address in Mycelium to sign a message with.
2) typed hi in the message field all lower case and no space at the end
3) created the signature.
4) downloaded and installed bither
5) put the appropriate address, message, and signature in the verify message fields.
6) received error that it was not a valid signature
Any thoughts or comments here are appreciated as I believe that the ability to prove ownership of the private keys of addresses with BTC associated with via messages signature is critical and this was the only way that I'm familiar with to be able to do so. Thanks.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

An in-depth overview of different mobile wallets

Disclaimer: A lot of time went into writing this and more research than I anticipated. Errors are not just possible, they are certain. If you find any mistakes, please reach out to me and I'll edit. Furthermore I know I probably missed a couple apps, there are a lot out there. If I missed a big one, then again contact me and I'll consider adding it. If you are reading this in the future, note that these apps update regularly, anything mentioned here may have changed by the time you are reading it.

What is a mobile wallet?

A mobile Bitcoin wallet is an application for a mobile device which acts as a lightweight wallet and allows you to store, send and receive Bitcoin (or other cryptocurrencies and tokens). Mobile wallets use SPV (Simplified Payment Verification) to allow wallet functionality without having to download the whole blockchain. This is very important as barely any mobile phones have enough storage space required for the full blockchain. Mobile wallets are also considered hotwallets, meaning they have an active connection to the internet. The mere fact of being 'online' allows for a number of attack vectors and as such should never be used to store large amounts. It is however not unsafe per se. Private keys are stored locally and encrypted. Some wallets keep backups of those encrypted private keys on a server of their own, and this is something to take note of, but not to fear. So without further ado, lets get to it. I focused on Android wallets, but many of the wallets mentioned here have iOS versions.

Coinomi No No 18 word seed A ton Custom No Advanced
Mycelium No No 12 word seed No Scrollwheel Tor Optional Intermediate

Wallet Breakdown

Samourai

Samourai focusses heavily on anonymity and obfuscation. Addresses are never used more than once. When making a transaction there is an obfuscation slider. Samourai has had SegWit enabled since October. Furthermore it offers a plethora of different features, too much to sum up here. If you are an advanced crypto-user you should definitely check out this wallet and their website which explains all of the different features. The UI takes a bit of getting used to though.

Breadwallet

Breadwallet is a very simple to use, straightforward app. The UI is slick and intuitive and in-app support to basic questions is very well incorporated. This could be a good wallet for a new person to the scene. The lack of advanced features will make this app not the go-to for more experienced users. It does however feature fingerprint authentication, which is cool, as well as BCH extraction. The lack of SegWit and complete absence of custom fee's is a problem though, especially since fees have gone up during the recent BTC spike. With only 2 fee options to choose from I simply can not recommend this wallet to people who are looking to make frequent transactions.

GreenAddress

When I first started with Greenaddress I didn't like the UI, I found it a bit clumsy. So definitely not user-friendly for a beginner. On the plus side it allows a choice of 2FA settings. Furthermore it has SegWit enabled and it has some advanced features like nLockTime transactions and it offers a service for instant transactions. This all feels very Lightning Network-y, which makes sense as GreenAddress is a part of Blockstream. Our friends in the other sub will most likely have something to say about this. I'll refrain from this and just say the following: this is an advanced wallet with promising features. If they clean up their UI a bit I could see myself using this without hesitation. The fact that they have MultiSig is a big plus as most mobile wallets do not have this functionality.

AirBitz

Unlike any other wallet I fired up at that point, this app did not prompt me with a 12- or 24-word seed. Instead it made me make an account, the regular username/password combo. After some research I found that these are not stored in a local database on their end. Which means that recovering your password in case of loss like with every other username/password login method we are so used to, is not possible. It is merely a different representation of an encryption key, allowing you access to your private keys. It features some interesting stuff though, NFC-compliant transactions and Bluetooth Low Energy (BLE) for example. Clearly this app is meant to be a bridge between users and merchants and has focus on making regular in-person transactions. Thus it mimics some non-crypto related payment apps that we have. Personally, I am not a fan, but I can appreciate the design philosophy and I would't be surprised if their design model worked very well in the future with the LN or with other crypto's that focus on small payments. As for the UI, it's fairly simple, yet horribly cluttered with partnered services. Good for non-techies maybe, but not for more experienced crypto-enthusiasts.

Electrum

Much like the desktop wallet I used years ago when I first started with Bitcoin, the mobile wallet is minimal. Straightforward and without fancy colors or UI. For those of us who have known the internet before Facebook, this app will feel strangely familiar. This is a classic example of a no-nonsense wallet with the features that really matter. SegWit and MultiSig enabled. A further lack of advanced options might be a turn-off for some users out there though. I did however find the option to spend coins from unconfirmed transactions. This could be very useful in case you want to cancel out a previously stuck or erroneous transaction and ensure it's never cleared. One downside to this wallet is the very primitive way of setting a custom fee. No guidelines, scrollwheel or info. Just a simple box in which to put your fee which won't help intermediate users, only experienced users.
Edit: sidenote on the SegWit implementation by Electrum http://www.crypto-economy.net/electrum-3-0-enables-bech32-segwit-addresses/?lang=en

CoPay

Of all the apps I've tried up to this point, CoPay had the best initializing phase, succinctly explaining risk and security. I can not imagine a better intro to a wallet for a first time bitcoiner. It being of a product of BitPay, of which I am personally not a fan, I have to admit though. This app looks clean, feels fast and is easy to use. It successfully demystified MultiSig functionality in its UI and partnered services are not obtrusive in the design. Downsides are lack of fee setting possibilities and SegWit. The latter I really do not understand given their main core of business. If it wasn't for those last two points, I would not see why not to recommend this wallet.

ArcBit

This app dissapointed me a bit. It starts out of the box, not mentioning any backup seeds or tutorial on the wallet itself or Bitcoin. It has no SegWit, no MultiSig, a lack of features and whilst a backup seed can still be requested from the settings, I feel it is of the utmost importance that such a security measure is not quickly overlooked. The lack of fee management tops it off. While this wallet works just fine and looks just fine, there are too many alternatives out there with better options and functionality for me to ever advise anyone to use this wallet.

CoinSpace

CoinSpace is one of those apps that could be really cool, but completely missed the boat on some other design choices. In-app ads unless you pay 1.6$ or something. Settings hidden behind a CoinSpace login screen. It features multiple tokens though with built in conversion through ShapeShift, which could have been awesome. But the excessive ads are just a big no-no. Lack of SegWit and limited fee options make this one of the least interesting wallets out there.

Simple Bitcoin Wallet

Simple Bitcoin is a very basic, barebone wallet. Feels like a one-man project. Almost no settings possible at all. There's much better out there.

Bither

I oddly liked Bither because of its design that reminded me of websites from the 2005-ish era using lots of gradients. Its one of those apps that you either like or you don't. The UI is not bad, but could be better, there's some functionality hidden in the settings, but not enough to satisfy. One very useful feature is built in BCH and BCG extraction. This is the first app I encountered with built in Bitcoin Gold access. It also has a separate tab with just market price information, which is really useful for the price ticker addicts among us. Furthermore it features Cold/Hot Storage View which allows you to monitor cold storage and with a nice graph shows you the distribution between Hot and Cold. Cool stuff. I would suggest to check it out, I'm sure some people will like and some won't. Do note, no SegWit. I would personally use this as a view-wallet only. Not as a spending wallet.

GreenBits

GreenBits is like the light version of GreenAddress. I tried looking for why one team would make 2 wallets but could not find a definitive answer asides from GreenBits being Android-native. And while some resources state MultiSig functionality and Tor through Orbot, I couldn't find those in this app. It does however sport SegWit and custom fees like GreenAddress. On the UI front I feel much more comfortable with this app though and I could see it being better received by average users. Looks like a good spending wallet without much extra.

Jaxx

Jaxx is a rather large wallet that supports many many many different coins with built in ShapeShift functionality. It did suffer from a hack earlier this year which is why this wallet has been discredited. I would however suggest looking into this one if you are invested in multiple different coins and regularly swap between them to get some financial edge. Lack of SegWit and fee options don't make this an ideal app for Bitcoin-only users.

Xapo

Xapo, known for its cold storage solutions was one of the apps I was eager to check out. Upon starting I however first had to verify through a text message, giving up my phone number, after which I was greeted by a 'Continue with Facebook or email' - screen. Upon choosing email, I was further asked to give up personal information. Nothing personal against these types of business models, but this is not what I am looking for in a mobile wallet. Centralization of personal information is quite in contrast with the decentralized and pseudonymous qualities of cryptocurrencies. This being the 13th wallet I've fired up tonight, I decided to give this one a pass.

Coinomi

Coinomi is very similar to Jaxx in the way that it supports a crapload of different currencies and in-app conversions between different tokens through ShapeShift and additionally Changelly. It does look quite a bit more straightforward though. A good alternative to Jaxx for those multicrypto traders among us. Unfortunately yet again not the best for straight Bitcoiners due to lack of SegWit. It has custom fees though, but much like Electrum, there's no real help here and it's just a manual input.

Mycelium

Mycelium has been my wallet app for a couple years now. Unfortunately the delay in SegWit adoption has me looking elsewhere and in succession writing this article. I really liked the recent addition of the fee scrollwheel, which is still the most detailed and succesful implementation of custom fees in any app I've seen. Having tried out many other apps at this point I can now see Mycelium, while not particulary user-unfriendly, could still very much improve its UI. It is however not a bad wallet, never crashed on me, always ran smooth through multiple updates. But let's not get sentimental here, it's a solid app, but its time for me and maybe you as well to try out something different ;-)

Conclusion

In this excruciatingly long article I've ran through a couple different wallet apps. One thing to learn is that not a single one of these is perfect and there's still room for improvement on many fronts. Which wallet holds your preference today depends largely on what you are looking for in a wallet. Do you want the cheapest transactions, then go for one of the SegWit enabled wallets. Do you like cool functionality, then check out Bither. Is anonymity of a concern to you then Samourai looks like the clear winner. More into multiple coins at once, then Coinomi or Jaxx is the way to go. And this is mobile wallets only, you have your desktop wallets, hardware wallets, cold storage solutions, paper wallets. But I'm all out of ink tonight!
I can't give you specific advice. In this world of cryptocurrencies we are in control of our own money. Being in control of your own money means being responsible for its security too. So make your own decision and due diligence.
Edit: Thanks everyone for the awesome responses. I've had some requests to further mention some important information regarding the wallets. I will write these down here as a memo to myself in the future, at which point I will review the state of mobile apps in greater detail once again. - Open Source or not - iOS version or not - Adding iOS only wallet apps

/r/Bitcoin FAQ - Newcomers 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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Additional Bitcoin statistics can be found here. Developer resources can be found here and here. Peer-reviewed research papers can be found here and here. And of course, the whitepaper that started it all :)

Where can I buy bitcoins?

You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, more can be found here.
Here is a listing of local ATMs. Also, Lawnmower is also a handy way to make small recurring purchases of bitcoin. If you would like your paycheck auotmatically converted to bitcoin use Cashila or 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. Here are a couple useful sites (bitkoin.io, preev.com) 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, usually from a text message or app, 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.

What is a Cryptocurrency Wallet?

What is a Cryptocurrency Wallet?
Use this straightforward guide to learn what a cryptocurrency wallet is, how they work and discover which ones are the best on the market.
A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency, you will need to have a digital wallet.
How do they work?
Millions of people use cryptocurrency wallets, but there is considerable misunderstanding about how they work. Unlike traditional ‘pocket’ wallets, digital wallets don’t store currency. In fact, currencies don’t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain.
Cryptocurrency wallets are software programs that store your public and private keys and interface with various blockchain so users can monitor their balance, send money and conduct other operations. When a person sends you bitcoins or any other type of digital currency, they are essentially signing off ownership of the coins to your wallet’s address. To be able to spend those coins and unlock the funds, the private key stored in your wallet must match the public address the currency is assigned to. If public and private keys match, the balance in your digital wallet will increase, and the senders will decrease accordingly. There is no actual exchange of real coins. The transaction is signified merely by a transaction record on the blockchain and a change in balance in your cryptocurrency wallet.
What are the different types of Cryptocurrencywallets?
There are several types of wallets that provide different ways to store and access your digital currency. Wallets can be broken down into three distinct categories – software, hardware, and paper. Software wallets can be a desktop, mobile or online.
Are Cryptocurrency wallets secure?
Wallets are secure to varying degrees. The level of security depends on the type of wallet you use (desktop, mobile, online, paper, hardware) and the service provider. A web server is an intrinsically riskier environment to keep your currency compared to offline. Online wallets can expose users to possible vulnerabilities in the wallet platform which can be exploited by hackers to steal your funds. Offline wallets, on the other hand, cannot be hacked because they simply aren’t connected to an online network and don’t rely on a third party for security.
Although online wallets have proven the most vulnerable and prone to hacking attacks, diligent security precautions need to be implemented and followed when using any wallet. Remember that no matter which wallet you use, losing your private keys will lead you to lose your money. Similarly, if your wallet gets hacked, or you send money to a scammer, there is no way to reclaim lost currency or reverse the transaction. You must take precautions and be very careful!
Although Bitcoin is by far the most well-known and popular digital currency, hundreds of newcryptocurrencies (referred to as altcoins) have emerged, each with distinctive ecosystems and infrastructure. If you’re interested in using a variety of cryptocurrencies, the good news is, you don’t need set up a separate wallet for each currency. Instead of using a cryptocurrency wallet that supports a single currency, it may be more convenient to set up a multi-currency wallet which enables you to use several currencies from the same wallet.
Are there any transaction fees?
There is no straightforward answer here.
In general, transaction fees are a tiny fraction of traditional bank fees. Sometimes fees need to be paid for certain types of transactions to network miners as a processing fee, while some transactions don’t have any fee at all. It’s also possible to set your own fee. As a guide, the median transaction size of 226 bytes would result in a fee of 18,080 satoshis or $0.12. In some cases, if you choose to set a low fee, your transaction may get low priority, and you might have to wait hours or even days for the transaction to get confirmed. If you need your transaction completed and confirmed promptly, then you might need to increase the amount you’re willing to pay. Whatever wallet you end up using, transaction fees are not something you should worry about. You will either pay minuscule transaction fees, choose your own fees or pay no fees at all. A definite improvement from the past!
Are cryptocurrency wallets anonymous?
Kind of, but not really. Wallets are pseudonymous. While wallets aren’t tied to the actual identity of a user, all transactions are stored publicly and permanently on the blockchain. Your name or personal street address won’t be there, but data like your wallet address could be traced to your identity in a number of ways. While there are efforts underway to make anonymity and privacy easier to achieve, there are obvious downsides to full anonymity. Check out the DarkWallet project that is looking to beef up privacy and anonymity through stealth addresses and coin mixing.
Which Cryptocurrency wallet is the best?
There is an ever-growing list of options. Before picking a wallet, you should, however, consider how you intend to use it.
Bread Wallet
Bread Wallet is a simple mobile Bitcoin digital wallet that makes sending bitcoins as easy as sending an email. The wallet can be downloaded from the App Store or Google Play. Bread Wallet offers a standalone client, so there is no server to use when sending or receiving bitcoins. That means users can access their money and are in full control of their funds at all times. Overall, Bread Wallet’s clean interface, lightweight design and commitment to continually improve security, make the application safe, fast and a pleasure to use for both beginners and experienced users alike.
Mycelium
Advanced users searching for a Bitcoin mobile digital wallet, should look no further than mycelium. The Mycelium mobile wallet allows iPhone and Android users to send and receive bitcoins and keep complete control over bitcoins. No third party can freeze or lose your funds! With enterprise-level security superior to most other apps and features like cold storage and encrypted PDF backups, an integrated QR-code scanner, a local trading marketplace and secure chat amongst others, you can understand why Mycelium has long been regarded as one of the best wallets on the market.
Exodus
Exodus is a relatively new and unknown digital wallet that is currently only available on the desktop. It enables the storage and trading of Bitcoin, Ether, Litecoins, Dogecoins and Dash through an incredibly easy to use, intuitive and beautiful interface. Exodus also offers a very simple guide to backup your wallet. One of the great things about Exodus is that it has a built-in shapeshift exchange that allows users to trade altcoins for bitcoins and vice versa without leaving the wallet.
Copay
Created by Bitpay, Copay is one of the best digital wallets on the market. If you’re looking for convenience, Copay is easily accessed through a user-friendly interface on desktop, mobile or online. One of the best things about Copay is that it’s a multi-signature wallet so friends or business partners can share funds. Overall, Copay has something for everyone. It’s simple enough for entry-level users but has plenty of additional geeky features that will impress more experienced players as well.
Jaxx
Jaxx is a multi-currency Ether, Ether Classic, Dash, DAO, Litecoin, REP, Zcash, Rootstock, Bitcoin wallet and user interface. Jaxx has been designed to deliver a smooth Bitcoin and Ethereum experience. It is available on a variety of platforms and devices (Windows, Linux, Chrome, Firefox, OSX, Android mobile & tablet, iOS mobile & tablet) and connects with websites through Firefox and Chrome extensions. Jaxx allows in wallet conversion between Bitcoin, Ether and DAO tokens via Shapeshift and the import of Ethereum paper wallets. With an array of features and the continual integration of new currencies, Jaxx is an excellent choice for those who require a multi-currency wallet.
Armory
Armory is an open source Bitcoin desktop wallet perfect for experienced users that place emphasis on security. Some of Armory’s features include cold storage, multi-signature transactions, one-time printable backups, multiple wallets interface, GPU-resistant wallet encryption, key importing, key sweeping and more. Although Armory takes a little while to understand and use to it’s full potential, it’s a great option for more tech-savvy bitcoiners looking to keep their funds safe and secure.
Trezor is a hardware Bitcoin wallet that is ideal for storing large amounts of bitcoins. Trezor cannot be infected by malware and never exposes your private keys which make it as safe as holding traditional paper money. Trezor is open source and transparent, with all technical decisions benefiting from wider community consultation. It’s easy to use, has an intuitive interface and is Windows, OS X and Linux friendly. One of the few downsides of the Trezor wallet is that it must be with you to send bitcoins. This, therefore, makes Trezor best for inactive savers, investors or people who want to keep large amounts of Bitcoin highly secure.
Ledger Nano
The Ledger Wallet Nano is a new hierarchical deterministic multisig hardware wallet for bitcoin users that aims to eliminate a number of attack vectors through the use of a second security layer. This tech-heavy description does not mean much to the average consumer, though, which is why I am going to explain it in plain language, describing what makes the Ledger Wallet Nano tick. In terms of hardware, the Ledger Wallet Nano is a compact USB device based on a smart card. It is roughly the size of a small flash drive, measuring 39 x 13 x 4mm (1.53 x 0.51 x 0.16in) and weighing in at just 5.9g.
Pros:
Cons:
Green Address
Green Address is a user-friendly Bitcoin wallet that’s an excellent choice for beginners. Green Address is accessible via desktop, online or mobile with apps available for Chrome, iOS, and Android. Features include multi-signature addresses & two-factor authentications for enhanced security, paper wallet backup, and instant transaction confirmation. A downside is that Green Address is required to approve all payments, so you do not have full control over your spending
Blockchain (dot) info
Blockchain is one of the most popular Bitcoin wallets. Accessing this wallet can be done from any browser or smartphone. Blockchain.info provides two different additional layers. For the browser version, users can enable two-factor authentication, while mobile users can activate a pin code requirement every time the wallet application is opened. Although your wallet will be stored online and all transactions will need to go through the company’s servers, Blockchain.info does not have access to your private keys. Overall, this is a well-established company that is trusted throughout the Bitcoin community and makes for a solid wallet to keep your currency.

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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin 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.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io
itBit
Bitit
Bitsquare
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or 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.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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
Android Android
iOS iOS

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss.

Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. Bitseed is an easy option for getting set up. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin ?BTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (?L) or micrometre (?m)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits
For more information check out the Bitcoin units wiki.
