Not all countries in the world are accepting the crypto, they have many reasons for not enjoying the crypto. like because of their banks, because they do not know any taxpayers. many reasons. but it would be legal to all countries.
Some countries have protective laws that bans any kind of currencies and it will take to amend or repeal the law if that government changed its mind and decided to allow cryptocurrency in their area. Other nations will eventually legalized bitcoin after some studies conducted by their monetary team. Tgere many reasons why some countries will continue to ban bitcoin but I believe that their would not last long.
