What is cryptocurrency?

Cryptocurrency is a type of payment that can be exchanged online for goods and services. Many companies have issued their own currency, often called a token, and this can be traded specifically for the good or service that the company provides. Think of them as if you were arcading tokens or casino chips. In order to access good or service you will have to exchange real currency for cryptocurrency. Cryptocurrencies operate using a technology called blockchain. Blockchain is a decentralized technology spread across many computers that manages and records transactions. Part of the appeal of this technology is its safety.
