If I'm an american and want to buy something in china, I need to pay renminbi. Typically this happens via some proxy financial institution, who will process the transaction through the various distributed global currency markets. The same could be true in the future of crypto, although national borders may not be the defining trait, but rather the relative properties of a currency and preferences of the sender or recipient. There are enough nuances between crytpocurrencies that there is room for more than a handful.
