$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It operates on a decentralized, peer-to-peer blockchain network, allowing users to send and receive digital money without intermediaries like banks. Bitcoin has a limited supply of 21 million coins, which makes it scarce and often compared to digital gold. It uses a proof-of-work (PoW) consensus mechanism, secured by miners. BTC is widely used for investment, trading, and as a store of value. Its price is highly volatile and influenced by global demand, regulation, and macroeconomic trends.
