What Is Cryptocurrency?
-----------------------

A cryptocurrency is a digital or [virtual currency](https://www.investopedia.com/terms/v/virtual-currency.asp) that is secured by cryptography, which makes it nearly impossible to counterfeit or double-spend. Many cryptocurrencies are decentralized networks based on [blockchain](https://www.investopedia.com/terms/b/blockchain.asp) technology—a [distributed ledger](https://www.investopedia.com/terms/d/distributed-ledgers.asp) enforced by a disparate network of computers. 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.

### Key Takeaways

*   Experts believe that blockchain and related technology will disrupt many industries, including finance and law.
    
*   The advantages of cryptocurrencies include cheaper and faster money transfers and decentralized systems that do not collapse at a single point of failure.
