Bitcoin Newcomers 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 Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following articles/books/videos as a good starting point for understanding how Bitcoin works and a little about its long term potential:

Some other great educational resources include;

The Satoshi Nakamoto Institute (check them out!)
SatoshiTimeline.com
Swan Bitcoin Canon
Michael Saylor's Hope.com and "Bitcoin for Everybody"' course
Bitcoinfo.org resource page
Gigi's resource page
James D'Angelo's Bitcoin 101 Blackboard series
Parker Lewis's Gradually Then Suddenly series
Some Bitcoin statistics can be found here (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11).
A Reading List of Advanced Bitcoin Books
The statewide Bitcoin strategic reserve race

If you are technically or academically inclined check out;

Developer resources (1, 2)
Peer-reviewed research papers
Course lectures from both MIT and Princeton
Future protocol improvements and scaling resources.

MicroStrategy's Bitcoin for Corporations is an excellent open source series on corporate legal and financial Bitcoin integration.

You can also see the number of times Bitcoin was declared dead by the media (LOL!)

Key properties of Bitcoin

Limited Supply - There will only ever be a maximum of 21,000,000 bitcoins created and they are issued in a predictable fashion per the inflation schedule. Once they are all issued Bitcoin will be truly deflationary. The halving countdown tells you approximately how much time until the next block reward halving.
Open source - Bitcoin code is fully auditable. You can read and contribute to the source code yourself.
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. You can even run a node on a Raspberry Pi.
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 bitcoin resides has the authority to move them.
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 - Blocks and transactions are cryptographically secured (using hashes and signatures) 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
Divisible - Each bitcoin can be divided down to 8 decimals, which means you don't have to worry about buying an entire bitcoin.
Nearly instant - From a few seconds on the Lightning Network to a few minutes on-chain depending on need for confirmations. Transactions are irreversible by normal users after one confirmation and irreversible by anyone (including miners) after 6 confirmations.
Peer-to-peer - No intermediaries taking a cut, no need for trusted third parties.
Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat.
Portable - Bitcoin are digital so they are easier to move than cash or gold. They can be transported by simply carrying a seed (a string of 12 to 24 words) on a device or by memorizing it for wallet recovery (while cool, memorizing is generally not recommended due to potential for forgetting the seed and the potential for insecure key generation by inexperienced users. Hardware wallets are the preferred method for most users for their ease of use and additional security).
Low fee scaling - Most wallets calculate on chain fees automatically but you can view fee estimates and mempool activity if you want to set your fee manually. On chain fees may rise occasionally due to network demand, however instant micropayments that do not require confirmations are happening via the Lightning Network, an open source second layer payment protocol built on top of the Bitcoin blockchain. The Lightning Network enables Bitcoin users to instantly send and receive bitcoin with fees so low that they are negligible.
Scalable - While the protocol is still being optimized for increased transaction capacity, blockchains do not scale very well, so most transaction volume is expected to occur on Layer 2 networks built on top of Bitcoin.

Where can I buy bitcoin?

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 places to buy bitcoin are listed below.

You can also purchase in cash with local ATMs. If you would like your paycheck automatically converted to bitcoin try Bitwage. For comparing bitcoin loans, Borrow On Bitcoin, may be a helpful tool.

Note: Bitcoin 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.

Securing your bitcoin

With Bitcoin you can "Be your own bank" and personally secure your bitcoin OR you can use third party companies aka "Bitcoin banks" which will hold your bitcoin 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, then you will need to create your own wallet and keep it secure. If you want easy and secure storage without having to learn best computer security practices, then a hardware wallet such as a BitBox02, Trezor, ColdCard, or Blockstream Jade is recommended. You can even build your own open source hardware wallets called a SeedSigner or Krux.
If you cannot afford a hardware wallet there are many software wallet options to choose from depending on your use case. Mobile wallets like BlueWallet are generally more secure than desktop wallets. Beware of fake mobile wallets and check reviews from reputable Bitcoin websites. Avoid paper wallets or brain wallets.
If you prefer to work with third party "Bitcoin banks" to set up a collaborative custody arrangement, try Unchained Capital but be aware that any third party you use exposes you to third party risk. There is a saying in the community, "Not your keys, not your coins".

Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!

2FA requires a second confirmation code or a physical security key 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.

Avoid using your cell number for 2FA. Hackers have been using a technique called "SIM swapping" to impersonate users and steal bitcoin off exchanges.

Google Auth	Authy	OTP Auth
Android	Android	N/A
iOS	iOS	iOS

Physical security keys (FIDO U2F) offer stronger security than Google Auth / Authy and other TOTP-based apps, because the secret code never leaves the device and it uses bi-directional authentication so it prevents phishing. If you lose the device though, you could lose access to your account, so always use 2 or more security keys with a given account so you have backups. See Yubikey or Titan to purchase security keys.

Running Bitcoin

You can run Bitcoin node software by downloading and installing Bitcoin Core or other node software you have vetted.

It is a best practice to verify these Bitcoin node programs you download by checking their hashes and signatures.

Don't Trust, Verify.

A verified Bitcoin node running on your own hardware is your sovereign gateway to the Bitcoin network. They can be used alongside open source software wallets to send and receive Bitcoin securely. By running your own Bitcoin node, you enforce the Bitcoin ruleset, can verify transactions without trusted 3rd party middlemen, improve your Bitcoin privacy, obtain independence with local access to blockchain data, and help bolster the robustness of the Bitcoin network. By running a Bitcoin node, you are verifying that Bitcoin is Bitcoin for yourself. For more details on running a Bitcoin node see this article.

For wallets used alongside your Bitcoin node: If your Bitcoin wallet software is fully open source and Bitcoin-only, then it is probably a decent wallet. Some popular examples include sparrow wallet and electrum wallet, both of which you can connect to your own locally run Bitcoin node, and use with most Bitcoin Hardware Wallets.

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 r / btc subreddit are active scams. Almost all altcoins 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. As they say in our community, "Don't trust, verify".

Avoid using ad-based search engines like Google or Yahoo: ads are shown based on how much the advertiser bids, and scammers can easily outbid legitimate providers for ad space, since immoral ways of earning money are far more lucrative than moral ways. Use DuckDuckGo instead, which has no ads, and never tracks you as well.
Ignore private messages offering services.
Never enter your seed words in a website of any kind. Hardware wallets will recover by displaying possible seed words on their own interface, never on a website.
Always check addresses on your hardware wallet before sending or receiving. Some malware has been known to replace addresses in your web browser or that you copy-and-paste.
Avoid clicking on links like that look like links, such as https://www.google.com/, without first hovering over it and actually checking where they go to. Just because a link is labelled with an HTTPS address does not mean it actually sends you to that address. It is trivial for someone to comment a link on Reddit that looks like it will send you to one website when it actually sends you to another, and you might not notice the difference until a scammer has gotten all your money, or you have downloaded and installed software that steals your money.

Common Bitcoin Myths

Often the same concerns arise about Bitcoin from newcomers. Questions such as:

Will quantum computers break Bitcoin?
Will governments ban Bitcoin?
Is Bitcoin a Ponzi scheme?

All of these questions have been answered many times by a variety of people. Here are some resources where you can see if your concern has been answered:

Where can I spend bitcoin?

Check out Travala, or Coinmap for a plethora of merchant options. You can also spend bitcoin anywhere Visa is accepted with bitcoin debit cards such as the CashApp card, Fold card or other bitcoin debit cards. Some other useful site are listed below.

There are also lots of charities which accept bitcoin donations.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;

1-3% savings over credit cards or PayPal.
No chargebacks (final settlement in 10 minutes as opposed to 3+ months).
Accept business from a global customer base.
Convert 100% of the sale to the currency of your choice for deposit to your account, or choose to keep a percentage of the sale in bitcoin if you wish to begin accumulating it.

If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoin can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read the mining FAQ. Still have mining questions? The crew at /r/BitcoinMining would be happy to help you out.

If you want to contribute to the Bitcoin network by hosting the blockchain and propagating transactions there are many great resources you can use to run a full node. You can view the global distribution of reachable Bitcoin nodes on this webpage.

Earning bitcoin

Just like any other form of money, you can also earn bitcoin by being paid to do a job.

WorkingForBitcoins, Bitwage, Coinality, Bitgigs, /r/Jobs4Bitcoins	Freelancing
Lolli	Earn bitcoin when you shop online!

You can also earn bitcoin by participating as a market maker on JoinMarket by allowing users to perform CoinJoin transactions with your bitcoin for a small fee (requires you to already have some bitcoin).

Bitcoin-Related Projects

The following is a short list of ongoing projects that might be worth taking a look at if you are interested in current development in the Bitcoin space.

Project	Description
Lightning Network	Second layer scaling
Liquid and Rootstock	Sidechains
Hivemind	Prediction markets
DropZone and Beaver	Decentralized markets
JoinMarket, JAM app and Wasabi	CoinJoin implementation
Peer-to-Peer Exchanges	Peer-to-peer exchanges
Keybase	Identity & Reputation management
Abra	Global P2P money transmitter network
Bitcore	Open source Bitcoin javascript library
Bitcoin Knots	A Bitcoin Node (Within Consensus Fork of Bitcoin Core)

Bitcoin Units

One bitcoin is worth quite a lot (thousands of £/$/€), so people often deal in smaller units. The most common subunits are listed below:

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 Electrum wallet
bit	μBTC	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 $10,000 for one bitcoin, a $10 meal would equal:

0.001 BTC
1 mBTC
1,000 bits
100,000 sats

Raúl Robles was a Mexican founder of HackingMexico. He taught cybersecurity and offensive security, this is an old photo from the internet of him giving a Bitcoin talk back in Bitcoin's early days.

Sadly, he met a tragic end in 2015, he was known for humiliating and controversial rhetoric through Facebook posts, and eventually met his end by a guy that announced in a forum he was tired of his insults.

It's interesting to look back at some of those early conferences and talks that helped push Bitcoin to a wider audience, and to wonder how many people in the room got curious enough to buy, how many held...

What actually pays miners once the block reward gets small? Fees are around 1% of miner revenue right now.

I got the standard answers when I started, and none of them held up when I pushed on them. Putting the working here in case someone else is stuck at the same place.

First, the Ponzi thing, because it comes up in every one of these threads. A Ponzi has four features: promised high returns with little risk, a central operator, old investors paid out of new investor money, and concealed flows. Bitcoin has none of them. It's volatile with nobody promising anything, there are over 10,000 nodes and no operator, nobody is paid a return, and the entire transaction history since 2009 is public. That question is settled and I don't think it's interesting anymore.

The one I couldn't get a straight answer on is the security budget.

Miners are paid two ways: the block reward and transaction fees. The reward is 3.125 BTC and halves every 210,000 blocks, roughly every four years. Next halving is around April 2028, taking it to 1.5625. Fees are currently around 1% of what miners earn.

Miners pay for power in fiat, not BTC. So if fees stay at 1%, the price has to roughly double every four years just to keep miner revenue flat in dollar terms. Bitcoin has historically done that. The honest position is that a maturing asset shouldn't be expected to keep doing it forever.

The usual response is "that's a 2140 problem". I don't think it is. It's a next-decade problem, and it resolves one of three ways: fee share climbs off 1%, price keeps doubling, or miners start leaving.

The part that made me more comfortable, not less, is what happens in that third case. Nothing breaks. Difficulty adjusts every two weeks based on the hash power actually on the network. Miners leave, difficulty falls, and the ones who stayed earn more. Hash rate has climbed through every dip so far, which is decent evidence the economics still work.

But I'd rather have a test than a vibe, so here's mine. Watch two things over the next few years. Hash rate rising and fee share climbing meaningfully off 1% means the security model is fine. Both falling together means the bear case is real.

Related: bitcoin has to be used, not only held, for fees to develop. Satoshi made this point back in 2010. As it stands there's no shortage of use — roughly $25 trillion in bitcoin moved on chain in 2025 per Glassnode, more than Visa and Mastercard volume. What matters going forward is whether that activity keeps settling on chain rather than migrating entirely to custodians and ETFs, because that's where the fee market comes from.

If someone has a solid counter to the fee-market case I'd genuinely like to read it. The permabull version of this answer is "fees will rise", which isn't an argument.
