$BTC BTC, the symbol for Bitcoin, represents the first and most well-known cryptocurrency. Launched in 2009 by the pseudonymous creator Satoshi Nakamoto, Bitcoin introduced a decentralized, peer-to-peer digital currency powered by blockchain technology. It allows secure, transparent transactions without the need for intermediaries like banks. $BTC has become a store of value, often referred to as "digital gold," and is used for both investment and payments. Its limited supply of 21 million coins drives scarcity and demand. Despite volatility, Bitcoin continues to influence the global financial system, sparking innovation, debate, and the rise of a new digital asset economy.
