$BTC the ticker symbol for Bitcoin, represents the first and most well-known cryptocurrency in the world. Launched in 2009 by the pseudonymous creator Satoshi Nakamoto, Bitcoin introduced a decentralized, peer-to-peer digital currency that operates without the need for a central authority. Powered by blockchain technology, $BTC is often seen as digital gold—a store of value and hedge against inflation. Its limited supply of 21 million coins and growing institutional adoption have cemented its role as a cornerstone of the crypto ecosystem.
