Bitcoin is a decentralized digital currency that lets people send value over the internet without a bank or middleman.
Bitcoin runs on a blockchain, a public ledger maintained by a global network of computers. Transactions are grouped into blocks and secured by a process called mining.
There will only ever be 21 million Bitcoin. This fixed supply is a core part of its design and value proposition.
Bitcoin gives anyone with an internet connection the ability to hold and transfer value that no government or company can seize or inflate away.
Buy Bitcoin on an exchange, then withdraw it to a wallet you control, ideally a hardware wallet for larger amounts.
Bitcoin is the first and largest cryptocurrency, and it introduced the idea of money that no single party controls.
