$BTC Bitcoin (BTC) is a decentralized digital currency that allows people to send and receive money over the internet without relying on banks or governments. It was introduced in 2009 by an unknown person or group using the name Satoshi Nakamoto. Bitcoin transactions are recorded on a public ledger called the blockchain, which ensures transparency and prevents double-spending. It operates on a peer-to-peer network, meaning users directly interact with each other without intermediaries. Bitcoin is created through a process called mining, where powerful computers solve complex mathematical problems to validate transactions and secure the network. It has a limited supply of 21 million coins, making it resistant to inflation. Bitcoin is widely seen as both a digital currency and a store of value, often referred to as “digital gold.” Despite its volatility, Bitcoin has gained global popularity and is used for investment, online purchases, and transferring money across borders.
