Cryptocurrencies let you buy goods and services, use apps and games or trade them for profit. Here’s more about what cryptocurrency is and how it works.
Cryptocurrency (or “crypto”) is a digital currency used as an alternative payment method or as an investment. Cryptocurrencies get their name from the cryptographic techniques that enable people to buy, sell or trade them securely without the need for a controlling authority, such as a government or financial institutions.
For example, Bitcoin was developed primarily to be a form of payment that isn’t controlled or distributed by a central bank.
