Cryptocurrency, in overly simple terms, is basically internet money—the most popular form of which is Bitcoin. In more complicated terms, it’s a decentralized digital currency.

It still works like real money, but the transaction is publicly recorded for everyone to verify, and impossible to counterfeit.
