The first cryptocurrency is generally considered to be Bitcoin, which was created in 2009 by an individual or group of individuals using the pseudonym “Satoshi Nakamoto.” Bitcoin is a decentralized digital currency that allows for peer-to-peer transactions without the need for a centralized intermediary like a bank. It operates on a blockchain, which is a distributed ledger that records all transactions and is maintained by a network of nodes around the world. Since the creation of Bitcoin, many other cryptocurrencies have been developed, each with their own unique features and purposes.
