It still will. Those who banned crypto in their country will catch up once they realize that bitcoin is dominating the financing institutions in many parts of the world. It's just like any other tech that should be used by many people first until other follow next.
We cannot say that for now, I believe bitcoin is capable of becoming a global currency because of its degree of adaptation. As we can see now a days many people in different countries are now engaged in bitcoin. They are earning money through it. So for me it is not impossible for bitcoin to become a global currency.
