How crypto works?

That's a great question! While there are many different cryptocurrencies, most of them share a few key characteristics. Cryptocurrency is a type of digital currency that uses encryption to make transactions secure and protect against the duplication of the currency. In order to make a transaction using cryptocurrency, you need an address (an identifier) to send it from and a private key (a secret code) to send it with. These addresses can be long strings of letters and numbers, but they can also be as simple as an email address or a username.
