$BTC

Bitcoin (BTC) is the first and most well-known cryptocurrency, created in 2009 by an anonymous individual or group using the pseudonym Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, allowing users to send and receive digital money without the need for banks or intermediaries. Bitcoin is secured by a consensus mechanism called proof-of-work, where miners validate transactions and earn rewards. With a capped supply of 21 million coins, Bitcoin is often viewed as "digital gold" and a hedge against inflation. Despite volatility, it remains a major force in the global financial landscape and crypto economy.
