A cryptocurrency is a digital or virtual currency

 Cryptocurrency is a medium of exchange using cryptography to secure the transactions, to control the creation of additional units and verify the transfer of assets. The exact identity of the author remains a mystery. The name Satoshi Nakamoto is used by the person or group who created bitcoin, which was posted to a cryptography mailing list in 2008. Quoting from We Use Coins: Bitcoin is a digital currency that is being used increasingly all over the world. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin.

A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. 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.
