Bitcoin is the native asset of a decentralized payment network. BTC is transferred between users and is also used to pay transaction fees; this chart quotes it in US dollars.
History and development
Bitcoin began operating in 2009 from Satoshi Nakamoto’s proposal for peer-to-peer electronic cash. Instead of entrusting a ledger to a bank or other intermediary, participants verify and share transaction records. Payments and ownership became possible on a network without a central administrator.
Trading markets and an open development community subsequently expanded worldwide. A capped supply and declining issuance became defining features, while protocol changes depend on proposals and adoption by participants. USD and JPY charts value the same BTC in different currencies; they do not represent separate crypto assets.
