Crypto is a type of digital money that uses complex mathematical codes to keep it secure and control its creation. It's not controlled by any government or financial institution, so you can use it to buy things or send money to people anywhere in the world without worrying about exchange rates or fees. There are different kinds of crypto like Bitcoin, Ethereum, and Litecoin, and they all work on a system called a blockchain.
Buying and selling crypto can be done on special websites or apps, and the value of each kind of crypto can change a lot in a short amount of time, so it's important to be careful when you invest in it..
