In the future, countries that ban cryptocurrencies are likely to lift bans, because it is impossible to resist the development of technology and sooner or later, in order to keep up with other countries, they will have to recognize cryptocurrency.

Countries that forbid Bitcoin will to loss, because they are unable to compete with other countries, especially that country will not benefit from the cryptocurrency stock deposit. As we know, Bitcoin is a very fast growing asset.
