$BTC $BTC, or Bitcoin, is the world’s first and most well-known cryptocurrency, created by the pseudonymous Satoshi Nakamoto in 2009. Operating on a decentralized blockchain, Bitcoin enables peer-to-peer transactions without the need for intermediaries like banks. Its limited supply of 21 million coins makes it a deflationary asset, often referred to as "digital gold." $BTC is widely used for trading, investing, and as a store of value. Price volatility can be high, but its long-term growth has attracted institutional and retail investors alike. As the foundation of the crypto market, $BTC continues to influence trends, innovation, and global financial conversations.
