$BTC

Bitcoin (BTC) is a digital currency created in 2009 by an unknown person using the name Satoshi Nakamoto. It runs on a decentralized network called blockchain, which records all transactions publicly. Unlike traditional money, Bitcoin isn’t controlled by any government or bank. People can buy, sell, or trade BTC online, and it's stored in digital wallets. Transactions are verified by miners using powerful computers, and they earn BTC as a reward. Bitcoin is limited to 21 million coins, which adds to its value. It’s used for investment, online purchases, and as a way to transfer money globally with low fees.
