What is Bitcoin (BTC)?

Bitcoin (BTC) is the world's first and largest cryptocurrency, created in 2009 by an anonymous person or group using the pseudonym Satoshi Nakamoto. Bitcoin is decentralised digital money that works without a central bank or government — transactions are confirmed by a global network of miners.

Bitcoin is often called "digital gold" because its supply is capped at 21 million coins. This scarcity makes Bitcoin a popular store of value against inflation. Bitcoin uses Proof of Work consensus, and new coins are created through mining.
