Bitcoin is the first and most well-known cryptocurrency, often referred to as digital gold. Launched in 2009 by the pseudonymous Satoshi Nakamoto, it introduced a decentralized, peer-to-peer financial system. Bitcoin operates on a secure blockchain network, allowing transparent and irreversible transactions without intermediaries. Its limited supply of 21 million coins makes it inherently deflationary, attracting investors seeking a hedge against inflation. Bitcoin’s influence extends beyond finance—it sparked the global crypto movement and continues to shape policy, innovation, and debate. Despite market volatility, its adoption by institutions and countries signals long-term relevance. Whether as a store of value or means of exchange, Bitcoin remains at the heart of the crypto revolution.
