Bitcoin is still a new technology in the world and it cannot be denied that there are still many people who do not yet know the bitcoin especially in poor and developing countries. Now this world is still not ready to use the bitcoin. But in the next few years I think the world would be ready to accept bitcoin and crypto currency, because human being is a great at adjusting, many of those who have not received the bitcoin will receive bitcoin in the future.
So true, For now there are still many countries that are not ready to accept bitcoin, Likewise with my country.
But with the development of bitcoin technology, I think many countries have and will prepare to accept Bitcoin.
And I think sooner or later bitcoin will be used by all countries in the world. So prepare yourself from now
