It will be a loss of those countries, so I don’t think they will resort on doing that. And what’s the reason behind that they will ban crypto exchanges worldwide? Definitely, this is too far to be possible, in fact the number of crypto exchanges have been increasing in number so there’s no way that it will turn into possibility banning all crypto exchanges one day.

Bitcoin is decentralized in nature, those centralized exchanges won’t never be relevant to the growth of bitcoin. But these centralized exchanges will always make sure to have bitcoin on their list.
