@augustus The concept of a trans-national money, whether fiat or crypto or gold, sounds nice on paper but always causes more trouble than benefits.

If I'm in the US and I want to trade with China I should buy stuff with dollars here, ship it over to China and sell it for yuan, then use those yuan to buy stuff in China and ship it back here to sell for dollars.

All global trade could be performed in this fashion without any need for an international reserve currency of any kind, but of course that would force forex traders to stop gambling with the world economy and get real jobs instead which would basically be another shoah.
