$BTC Bitcoin (\$BTC) is the first and most well-known cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. It operates on a decentralized, peer-to-peer blockchain network, enabling secure and transparent transactions without the need for intermediaries like banks. Bitcoin is often seen as "digital gold" due to its limited supply of 21 million coins, making it a popular store of value and hedge against inflation. It has sparked widespread adoption, from individual investors to institutions, despite facing regulatory scrutiny and high volatility. Bitcoin continues to shape the future of finance and remains a key driver in the cryptocurrency market.
