Many people use cryptocurrency and most of them are altcoins and tokens, I think so many people should know how to run it along But learn at the right time
On my opinion I think the world is either ready nor prepairing for the cryptocurrency just like here in my country. There are lots of people and company's here that accepting cryptocurrency these days. But there's also countries that do not accept the existence/presence of cryptocurrency. But I also agree to you that most people use altcoins and tokens.
