Bitcoin (BTC) is the world’s first decentralized digital currency, created in 2009 by the mysterious Satoshi Nakamoto. It operates without banks or central authorities, relying instead on blockchain technology — a public ledger that records all transactions. Bitcoin’s limited supply of 21 million coins makes it scarce and valuable, often referred to as “digital gold.” People use Bitcoin for investment, international transfers, and as an alternative to traditional money. Despite its price volatility, Bitcoin has captured global attention and inspired a new era of cryptocurrencies. As more individuals and institutions adopt Bitcoin, it continues to reshape how we think about finance, ownership, and the future of the global economy.
