Bitcoin is a cryptocurrency that was created in 2009 by Satoshi Nakamoto. It's the first decentralized digital currency, meaning it doesn't have any central authority or banks involved in its creation and maintenance. Instead, it relies on a peer-to-peer network of computers to verify and process transactions. Bitcoin has grown exponentially since its inception and is now worth over $10 billion.
