Imagine this scenario: you take an extended trip to three foreign countries. You dont exchange currencies or pay the fees to do so. You spend your money without ever taking it out of an ATM or paying international transaction fees.
Sounds convenient and cheap, right?
This scenario isnt a pipe dream. It could be the future of international currency.
Well actually it is already happening. With bitcoin in our stash and our destination are the three countries that greatly support Bitcoins, then we can just use our Bitcoin to pay for our expenses, either by converting them to the nation's money where we are at that current time.
