$BTC
Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing peer-to-peer transactions without intermediaries like banks. Bitcoin is secured through a process called mining, where powerful computers validate transactions and earn new coins. With a capped supply of 21 million coins, BTC is often seen as "digital gold" and a hedge against inflation. Its transparency, security, and limited supply have attracted investors, institutions, and tech innovators globally. Despite price volatility, Bitcoin remains a foundational asset in the evolving landscape of digital finance.
