Sooner or later all countries will make the cryptocurrency legal. Now it's better to deal with those cryptoexchanges that are in the jurisdiction of countries that are positive about the cryptocurrency.
In countries where people do not have access to a computer, them are not at all up to bitcoin. They are preoccupied with more elementary problems. On investment and financial literacy, there is nothing to say.
Closer to the autumn, cryptocurrencies start to grow. It is not known how big this growth will be. I'm also inclined to think that in the autumn bitcoin will cost $20.000, and by the end of the year $50.000
