$BTC

Bitcoin (BTC) is the first decentralized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a peer-to-peer network using blockchain technology, enabling secure, transparent transactions without intermediaries like banks. Bitcoin's supply is capped at 21 million, making it deflationary. Miners validate transactions through proof-of-work (PoW), earning BTC as rewards. Known for its volatility, Bitcoin is seen as "digital gold" and a hedge against inflation. Major institutions and investors now embrace it, though regulatory scrutiny remains. Its price is influenced by adoption, macroeconomic trends, and market sentiment. BTC remains the dominant cryptocurrency by market cap.
