Bitcoin is a digital currency that was created in 2009 by an unknown person or group of people using the pseudonym Satoshi Nakamoto. It is a decentralized form of currency, meaning that it is not controlled by any government or financial institution. Bitcoin transactions are recorded on a public ledger called the blockchain, which ensures transparency and security. Users can buy, sell, or exchange Bitcoin like any other currency, and its value fluctuates based on supply and demand in the market.
