$BTC Bitcoin (BTC) is the world’s first and most widely recognized cryptocurrency, launched in 2009 by the mysterious figure Satoshi Nakamoto. Built on a decentralized blockchain network, Bitcoin enables peer-to-peer transactions without the need for intermediaries like banks. It operates through a proof-of-work consensus mechanism, where miners validate transactions and secure the network. Often called “digital gold,” Bitcoin is valued for its limited supply of 21 million coins, making it an attractive hedge against inflation for some investors. Its price is highly volatile, driven by market demand, macroeconomic trends, regulatory developments, and institutional adoption. Bitcoin continues to shape the future of finance.
