Cryptocurrency is a digital currency that works as a currency of exchange through a computer network that isn’t centralized, like a government or bank. It uses cryptography to secure transactions on a decentralized ledger that can be viewed by any participant. Cryptocurrency can be exchanged in a trustless environment between two unknown parties. It can also be traded on cryptocurrency markets, which are exchanges that allow customers to trade cryptocurrencies for other assets, such as digital currencies or fiat money.
