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 that a unique currency could be a way to equalize markets. It will be quite beneficial for countries with low income or undeveloped ones because this way their governments will be forced to "play" and pay as others do and this will make less people move to other countries to work and leave children behind in grandparents care just to bring more money on the table.. Also, making a unique currency world-wide will be beneficial to the local producers. Instead of traveling to cheaper countries for groceries (like Danes that go to Germany or Romanians going to Bulgaria) will increase the local production and will give a bigger profit to the country market.
