What is Bitcoin (BTC/USD)?

Bitcoin is the world's first widely adopted decentralized cryptocurrency. The BTC/USD trading pair tracks the real-time value of one Bitcoin measured in United States Dollars, making it the most heavily traded and monitored digital asset metric globally.

Unlike traditional stocks or equity indexes tied to corporate earnings or a specific country's economy, Bitcoin operates on a borderless, peer-to-peer blockchain network with a hard-capped supply of 21 million coins. It trades around the clock and serves as the primary bellwether for the overall health and momentum of the broader cryptocurrency market.

Curiosity: On May 22, 2010, a programmer named Laszlo Hanyecz made the first documented commercial cryptocurrency transaction by paying 10,000 BTC for two Papa John's pizzas. At Bitcoin's modern highs, those two pizzas would be worth well over $700 million.
