$BTC Bitcoin (BTC) is the first and most well-known cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain, allowing peer-to-peer transactions without intermediaries like banks. Bitcoin's fixed supply of 21 million coins and its deflationary model make it appealing as a store of value. Over time, BTC has gained acceptance among investors, institutions, and even some governments. While it faces criticism for energy use and price volatility, its underlying technology has sparked innovation in finance and beyond. #Bitcoin continues to shape the future of digital currency and remains a symbol of financial independence.
