$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, enabling peer-to-peer transactions without intermediaries like banks. BTC is often called "digital gold" due to its limited supply of 21 million coins, making it a popular store of value. Its price is highly volatile, influenced by factors like adoption, regulation, and macroeconomic trends. Bitcoin is widely used for investments, remittances, and as a hedge against inflation. Despite criticisms over energy consumption and scalability, it remains the dominant crypto, shaping the future of decentralized finance.
