Lol cryptocurrency are already playing the role of real money, they are already a medium of exchange and that’s the main purpose they were created.

The problem is that people don’t really trust cryptocurrency, it’s still new and they don’t understand how it works yet and plus the fact that it is volatile is making lots of people to be scared of making use of it since they are likely to lose their money due to how the price fluctuates wildly. Some people have said that cryptocurrency (bitcoin) will become stable, but I don’t think that’s going to happen any time soon.
