I don't think Bitcoin is ready to be use globally. It still needs a lot of development and still needs to solve a lot of problem before it could be use without some major hassle like fees and transaction speed. It still need some time. Maybe in the near future, some developers would find a way.
Yes i think so,, bitcoin is not that perfect as it is,, but personally i believe everything the people, all countries and bitcoin itself will be ready globally at the right time,,hoping for more investors of btc,, its just the matter of time and im very optimistic with it,,,,
