#ProjectCrypto Bitcoin is a decentralized digital currency that operates without the need for a central bank or a single administrator. Users can make transactions directly with one another through a peer-to-peer network, eliminating the need for intermediaries. Transactions are secured using cryptography and recorded in a public ledger known as the blockchain. This cryptocurrency was created in 2008 by an individual or group using the pseudonym Satoshi Nakamoto, and the software became available as open-source in 2009.
