$BTC is the first and most widely recognized cryptocurrency, often seen as digital gold due to its limited supply of 21 million coins and decentralized nature. Built on blockchain technology, it enables peer-to-peer transactions without the need for intermediaries like banks. Bitcoin has grown from a niche tech experiment to a global financial asset, attracting investors, institutions, and governments alike. Its price is highly volatile, driven by market sentiment, macroeconomic trends, and adoption milestones, making it both a store of value and a speculative investment.
