I think the problem will even be from the laws and legal force in each country,since the laws are very different in the countries and finding a solution that will suit absolutely everyone will be unrealistic.I think for any user the most important thing is an exchange in two directions, and the laws and loyalty of the state are not so important.
All problems will always have a better solution when everyone is so aware of the laws and regulations in their respective countries, because in all countries there are always exchanges that have permission to operate smoothly enough so that it will not be difficult for those who want to accept Bitcoin like like receiving fiat money in life. So there is no need to worry about laws because when all countries and all people have accepted Bitcoin equally in their lives, of course there will also be special laws against it.
