Bitcoin was introduced in 2009 as open source software created by the pseudonymous Satoshi Nakamoto. It has a fixed supply of 21 million coins that are digitally mined by solving cryptographic problems to earn rewards. Transactions are recorded on a public blockchain using cryptography and stored in digital wallets identified by private and public keys. While bitcoin allows for easy international money transfers, it has limitations like wallet loss, price fluctuation, lack of physical form, and no central authority.
