What is cryptocurrency?

Cryptocurrency is a digital or virtual currency secured by cryptography, making it nearly impossible to counterfeit or double-spend.

Many cryptocurrencies are decentralized networks based on a specific technology – blockchain, a distributed ledger enforced by a disparate network of computers known as nodes.

A defining feature of cryptocurrencies is that they are generally not issued by any central authority, rendering them theoretically immune to government interference or manipulation.
