The way people work, interact, buy and even pay for things has changed with technology. Companies and customers no longer want cash, which makes room for contactless payments, such as Apple Pay. Users may pay for things in digital registries with the simple wave of a smartphone. There is now a new payment system: cryptocurrency.
Everybody probably heard about Bitcoin by now. It was the first widespread cryptocurrency, but other people are becoming more popular. Over 2,000 varieties of cryptocurrencies are present and more are being produced daily.
