I've been hearing a lot about cryptocurrency, but I don't really know what it is. Can you explain it?

Cryptocurrency is a digital currency that uses cryptography for security and authenticity. It typically does not have physical representation like paper bills or coins. Instead, cryptocurrency exists as data stored on computers or in other digital form. This means it can be used to buy things online, send money across the globe, and more. Cryptocurrency also has its own exchange rate, so it’s possible to make profits by selling your cryptocurrency at a higher value than you bought it for.
