Well, I hope this will be the case with many other countries too.... It is always a hassle to work with all these foreign currencies and no matter what you do, you always end up with some foreign spare
change, when you go back to your country of origin. The few pennies are not worth the effort and the fees to convert it at a exchange, so it ends up in a drawer somewhere. If you used Bitcoin, you
have no such problems.... the left of Satoshi's will always be in your wallet, ready to be used on your next trip.
