$BTC (Bitcoin) is the first and most well-known cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing peer-to-peer transactions without the need for banks or intermediaries. With a fixed supply of 21 million coins, Bitcoin is often referred to as “digital gold” due to its scarcity and store-of-value properties. It enables fast, borderless, and censorship-resistant transfers, and is secured by a proof-of-work consensus mechanism. $BTC has become a global financial asset, driving innovation in decentralized finance (DeFi) and influencing policy discussions on the future of money and financial freedom.
