Bitcoin is a decentralized digital asset whose transactions are recorded on a public blockchain. It allows value to be transferred without a central bank operating the network, but that does not make its price stable or its use risk-free.
How the network works
Transactions are authorized with cryptographic keys and grouped into blocks. Participants known as miners compete to validate blocks through proof of work, helping maintain agreement about transaction history.
Supply and ownership
The protocol limits the eventual supply of bitcoin. Ownership is controlled through private keys: losing a key can mean permanently losing access, while sharing it can allow someone else to transfer the funds.
Important risks
Bitcoin prices can change sharply. Exchanges and wallets introduce operational and security risks, transactions may be difficult to reverse, and legal or tax treatment varies by jurisdiction.
