Could you see a future wherein the entire world shares one global currency, be it fiat or crypto? If I think it in a scifi kind of way, it would most probably be some digital currency that could all just use. It doesn't even have to be in this century. Maybe the next?
the exact development is in line with the times and technology and it is possible that crypto currencies and fiat currencies can develop along with mutual benefits that maybe all we need is to be able to take advantage of opportunities to benefit from investing.
