$BTC

Bitcoin is a digital currency created in 2009 by an unknown person or group using the name Satoshi Nakamoto. It runs on a decentralized system using blockchain technology — a public ledger that records all transactions.

Unlike traditional currencies, Bitcoin is not controlled by any government or financial institution. It is secured through cryptography, and transactions are verified by network nodes through a process called mining.

Bitcoin is often seen as a store of value, like digital gold, and is used for investment, trading, and sometimes everyday purchases.
