$BTC Bitcoin (BTC) is the world’s first and most well-known cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, allowing secure and transparent transactions without the need for intermediaries like banks. Bitcoin is often referred to as "digital gold" due to its limited supply of 21 million coins and its appeal as a store of value. It has become a popular hedge against inflation and a foundation for the broader crypto market. Despite price volatility, Bitcoin continues to gain global acceptance among investors, institutions, and even governments.
