I think there is a bit of a miss here because until now bitcoin is not a global currency as you say.
In this case i still support bitcoin and when asking about how to tell that bitcoin is one of the investment assets that is quite feasible maybe this can still be done but to claim bitcoin of global currency is still very far away because now we are still in commodities and it cannot be said to be a global currency at this time.
The amount of miss information because indeed some people who have an interest do not want to make bitcoin look further with their power they are still trying to cover up the truth about bitcoin it will certainly still be very disturbing but in this case of course as long as there is internet and the development of technology is getting more comprehensive I think bitcoin will continue to grow and now also its development has looked very good.
I would argue that it is a "global" considering that the whole is using it right now, yes it's quite true that we should consider the situation to be a lot better and that would make sure that we should consider the situation a little different. I personally we should consider the best thing we could do at this point we could just consider the whole world using it, there are even users from the smallest nations and that's why that is quite important and that should be the key here.
I believe that people should consider to learn more and more about it, using it without consider the situation to be a lot more difficult and that should be a lot better for everyone if they all end up learning what they could do and we could definitely consider this as the betterment of bitcoin, it should always consider growing as a good thing and it would help bitcoin a lot, it might be used all around the world but that doesn't mean that it's understood all around the world as well.
