Cryptocurrency may as well be called "cryptic currency," because it's nowhere near as easy to figure out as typical money
Why do people always say that?
Bitcoin are easy to use. The biggest problem is to buy them on an exchange and that isn't even hard, if you have ever filled out a form for e.g. a bank account.
If you want to look further into the tech and not just using it, yes, it is complicated, but so is "typical" money or online banking.
