About Bitcoin
The original cryptocurrency and the largest by market capitalization.
Bitcoin is a peer-to-peer digital currency invented in 2008 by an anonymous developer using the pseudonym Satoshi Nakamoto. It runs on a decentralized network of computers worldwide and uses a consensus mechanism called proof-of-work to validate transactions without any central authority. Bitcoin is the largest and most widely-traded cryptocurrency on the planet, and the only one supported by every major exchange.
Bitcoin is used primarily as a store of value — often called "digital gold" — and as a hedge against inflation in countries with weak currencies. A growing number of merchants accept it directly, and major payment networks like Visa, PayPal, and Cash App allow customers to buy and hold Bitcoin. Institutional adoption has grown rapidly: spot Bitcoin ETFs are available in Canada (since 2021) and the US (since January 2024).
