About what is bitcoin
Bitcoin is digital money you can send to anyone in the world without a bank. It runs on a public network of thousands of computers that share one record of every transaction. No company controls it. The rules are enforced by software anyone can download and run. Bitcoin launched in January 2009 after an anonymous developer named Satoshi Nakamoto published its design in October 2008. It remains the largest and oldest cryptocurrency.
How it actually works
Every Bitcoin transaction is broadcast to a peer-to-peer network. Specialized computers called miners compete to bundle pending transactions into a block roughly every 10 minutes. The winning miner adds the block to the blockchain and earns newly created bitcoins plus fees. Once your transaction is buried under a few blocks, reversing it would mean redoing all that work. That is what makes Bitcoin's history practically tamper-proof. Only 21 million bitcoins will ever exist. The mining reward cuts in half every 210,000 blocks, which is about every four years. After the April 2024 halving the reward is 3.125 BTC per block.
Start here
- 1Install a wallet you control, like Phoenix, Muun, or BlueWallet.
- 2Buy a small amount on an exchange or earn some โ just enough to learn.
- 3Send it from the exchange to your own wallet. That is the moment you actually hold Bitcoin.
- 4Try a Lightning payment for a near-instant, sub-cent transfer.
Strengths
- Permissionless โ no one can block, freeze, or reverse your transaction.
- Fixed supply capped at 21 million coins, often called "hard money."
- Most battle-tested cryptocurrency, running continuously since January 2009.
Common misunderstandings
- The price is volatile and has dropped more than 70% in past cycles.
- On-chain fees spike during busy periods like the Ordinals and Runes mints.
- Self-custody means you lose the coins forever if you lose your recovery phrase.
Common questions
Who created Bitcoin?
Bitcoin was created by a developer or group using the name Satoshi Nakamoto. They published the Bitcoin whitepaper on October 31, 2008 and mined the first block on January 3, 2009. Satoshi's last public message was in December 2010. The last known private email, sent in April 2011, simply said "I've moved on to other things." Their real identity has never been confirmed.
How many bitcoins will ever exist?
The protocol caps the total supply at 21 million coins. New coins enter circulation as a mining reward that halves every 210,000 blocks, roughly every four years. After the April 2024 halving, the reward is 3.125 BTC per block. The last new bitcoin is projected to be mined around the year 2140.
Is Bitcoin actually private?
Bitcoin is pseudonymous, not anonymous. Every transaction is visible on the public blockchain forever, linked to wallet addresses instead of names. With enough analysis, addresses can often be tied back to real people, especially after coins pass through an exchange that does identity checks.
Why does Bitcoin have value?
Bitcoin has value because enough people worldwide agree that it does โ the same basic reason gold or fiat money holds value. Its fixed supply, censorship resistance, and global access are the main reasons supporters hold it. Critics argue it has no intrinsic value. The first known commercial purchase was 10,000 BTC for two pizzas on May 22, 2010 โ now called Bitcoin Pizza Day.
Can I lose money holding Bitcoin?
Yes. Bitcoin's price is volatile and has dropped 70% or more in past bear markets. You can also lose all of it by losing your wallet's recovery phrase, falling for a phishing scam, or sending coins to the wrong address. Transactions cannot be reversed.
