There are countries that might feel it’s not right for them, and they won’t accept them. But despite, we don’t really need every country in the world to accept it, there are already lots of countries around the world that accepts cryptocurrency and that is enough. Then I don’t understand what you mean by Bitcoin becoming a universal money, it will be widely accepted but it’s going to be an alternative to the currency we make use of, and other payment methods there is.

I make use of Bitcoin but I didn’t put all my money there, just those that needs to be there, majority of my money still has to be in the bank and that’s it.
