I think the fact that Bitcoin countries are banned from their country may be because they fear that if Bitcoin becomes a form of payment as their currency, then their currency may be devalued. And they may not yet see the economic impact of their country if Bitcoin is allowed.
Government will not say that they don't accept Bitcoin at anytime but they need some more time to accept cryptocurrencies to the part of their economic my opinion is it will definitely happen soon and government will accept Bitcoin at one time.
