What is Bitcoin?
Bitcoin (BTC) is the world's first cryptocurrency, launched in 2009. It runs on a blockchain with no central administrator, and its supply is capped at 21 million coins. A “halving” roughly every four years cuts new issuance in half, giving it a scarcity that earns it the nickname “digital gold.”
