$BTC Bitcoin (BTC) is a decentralized digital currency that operates without a central authority like a bank or government. It was invented in 2008 by an unknown person or group using the name Satoshi Nakamoto and launched in 2009. Bitcoin uses blockchain technology, a public ledger that records all transactions securely and transparently. It allows peer-to-peer transfers, meaning people can send and receive BTC directly without intermediaries. Bitcoin is limited to 21 million coins, which adds to its scarcity and value over time. It's used for investment, online purchases, and as a store of value, often referred to as "digital gold."
