$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology to record transactions securely and transparently. Unlike traditional currencies, Bitcoin is not controlled by any central authority, making it resistant to censorship and inflation. It has gained widespread adoption as both a digital asset and a store of value, often referred to as "digital gold." Bitcoin's limited supply (21 million coins) and growing institutional interest contribute to its volatile but upward-trending market presence.
