Is there a role for Bitcoin in international trade? Have you heard of a trade between two countries?
And will it be in the future?
It is unlikely that countries are going to use bitcoin to settle trades among them, that will basically be an endorsement to bitcoin and in a way they will be recognizing as well that they do not trust each other with their currencies and they prefer to choose a decentralized currency instead, so I really think that we are not going to see such a thing in our lifetimes.
