$BTC
Bitcoin (BTC) is the first and most prominent cryptocurrency, launched in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, which ensures transparency and security. Bitcoin is often viewed as digital gold due to its limited supply of 21 million coins. It has gained popularity as both a store of value and a medium of exchange. Despite its volatility and regulatory uncertainties, Bitcoin continues to attract investors, institutions, and advocates of financial freedom. It plays a central role in the broader crypto ecosystem and the ongoing evolution of decentralized finance (DeFi).
