Bitcoin is the first and most well-known cryptocurrency, created in 2009 by an anonymous person or group known as Satoshi Nakamoto. It operates on a decentralized, peer-to-peer network using blockchain technology, allowing secure and transparent transactions without intermediaries. Bitcoin is often seen as digital gold due to its limited supply of 21 million coins. It has gained global attention as both a store of value and a speculative investment. While its price is highly volatile, Bitcoin continues to attract institutional and retail investors, influencing the broader cryptocurrency market and reshaping the future of finance and decentralized digital assets.
