Bitcoin is the world's first and most widely recognized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. As a decentralized digital currency, Bitcoin operates on a peer-to-peer network without the need for intermediaries like banks or governments.
BTC is the native cryptocurrency of the Bitcoin network. It is used as a store of value, medium of exchange, and is often referred to as 'digital gold' due to its scarcity and deflationary properties.
