I don't think everybody will accept bitcoin in the next five years. The real problem is the government, regulators, and the bank. Instead of embracing blockchain technology, they have to protect their traditional system for "small" profit.
Yeah, that is really true. Government and the people who have power are the one that control what is happening in the country, they can regulate the cryptos if they want or they can feel come threats about it. And also another thing is that the people or the citizens of a country, some of it are want to use the traditional system or the fiat money because it is the thing that they use in their whole life and they dont want to change it.
