Cryptocurrency is different from traditional currency in that it is digital and decentralized. Cryptocurrency is created, stored, and managed through a public ledger system known as a blockchain, rather than a centralized institution like a bank. It also operates outside the control of governments and central banks. Transactions of cryptocurrency are secure and anonymous and can be done from anywhere in the world, instantly. Traditional currency, on the other hand, has physical notes and coins and is backed by governments and central banks. Transactions must typically pass through an intermediary such as a bank.
