$BTC Bitcoin (BTC) is the world’s first and most popular cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, allowing peer-to-peer transactions without a central authority. Bitcoin is often called “digital gold” due to its limited supply of 21 million coins and use as a store of value. Its price is highly volatile, influenced by global events, regulations, and market sentiment. Investors see it as a hedge against inflation and traditional finance. As adoption grows, Bitcoin continues to reshape the financial landscape, offering both opportunity and risk in the digital age.
