▲0.80%What Bitcoin is
Bitcoin is a decentralised digital currency launched in 2009 by a person or group writing under the name Satoshi Nakamoto. It runs on a public network of computers that agree on a shared ledger, so a payment can settle without a bank, a payment processor, or a government sitting in the middle.
New bitcoin enters circulation through mining, where computers compete to add the next block of transactions and are paid for doing it. That reward halves roughly every four years, and the total supply is capped at 21 million coins — a limit written into the software rather than set by anyone.
It is worth being clear about what Bitcoin is not. It is not fast: confirmations take minutes. It is not private: every transaction is permanently public. It is not stable: the price moves violently and has fallen more than 70% from a high on several occasions. It is best understood as a settlement network and a scarce digital asset, not a replacement for everyday payments.
About the asset
Bitcoin has no token contract — it is the native asset of its own chain, not a token issued on someone else's.
