I only travel outside the country maybe 3 to 4 times a year but whenever I do I wish there is just one currency that I could use whether it is "real" money or virtual money. I just think it would be more efficient if there is one common currency since the world is getting smaller anyway and traveling the world has been in vogue for quite some time now. I can use my credit card, yes, but it often makes me wonder how much money would I be charged at the end of the billing period if say the currency exchange changes a lot from the time I swiped my credit card. And well, I just don't want the bank charges. Is there a possibility for a crypto to be able to provide this service?
I think traveling outside the country 3 to 4x a year is already more than the average. I'm lucky if I get to do that once a year. Anyway, yes it would be great if there one currency that could be used anywhere. A private company may be able to do that if they have a lot of capital and influence in their hands. They could partner with the largest corporations so that their currency could be adopted worldwide. A crypto company would be a logical choice.
