$BTC Bitcoin ($BTC), created by the mysterious Satoshi Nakamoto in 2009, was the first cryptocurrency, sparking an entirely new financial era. Initially worth less than a cent, Bitcoin hit mainstream headlines in 2010 when two pizzas were famously bought for 10,000 BTC — a transaction now worth hundreds of millions. Bitcoin's limited supply of 21 million coins makes it digitally scarce, often compared to "digital gold." Its decentralized nature means no government controls it, fueling both adoption and controversy. Despite wild price swings, Bitcoin remains the largest crypto asset by market cap, and continues to influence global debates on money’s future.
