Bitcoin is a decentralized digital currency that uses cryptography for security and is not controlled by any government or financial institution. It was invented by an anonymous person or group of people known as Satoshi Nakamoto in 2009.
Bitcoin is based on a distributed ledger technology called blockchain, which allows it to operate without a central authority. Transactions are recorded on a public, decentralized ledger called a blockchain, which ensures that the same bitcoin cannot be spent twice by the same person.
Bitcoins can be bought and sold on online exchanges and stored in digital wallets. They can be used to make purchases online or transferred to other people. Transactions with bitcoin are fast and cheap, and they can be made without the need for a bank or other financial institution.
