Cryptocurrency is a digital or virtual currency that uses cryptography for security. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature. It is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems. The decentralized control of each cryptocurrency works through a blockchain, which is a public transaction database, functioning as a distributed ledger.
