Cryptocurrency is a type of digital or virtual currency that uses cryptography to secure transactions and control the creation of new units. Unlike traditional money, it is decentralized and operates on blockchain technology—a distributed and immutable public ledger.
How Does Cryptocurrency Work? Cryptocurrencies are powered by blockchain, a system that records all transactions across a network of computers. Every time someone sends or receives crypto, that transaction is added to a block and linked to the previous block—forming a chain.
