$BTC BTC, or Bitcoin, is the world’s first and most prominent cryptocurrency, launched in 2009 by the pseudonymous creator Satoshi Nakamoto. Built on blockchain technology, Bitcoin offers a decentralized, peer-to-peer system for transferring value without the need for banks or intermediaries. Often referred to as "digital gold," it is praised for its limited supply—capped at 21 million coins—which supports its appeal as a hedge against inflation. Bitcoin's price is highly volatile, influenced by factors like market sentiment, adoption rates, regulatory news, and macroeconomic conditions. Over time, $BTC has evolved from a niche technology to a major asset in global finance.
