Russians still use ruble, usd, rmb, yen, rupees and barter trade EASILY. Half the world trade data now gone dark. Just go read up Russians still working with Japanese on the oil rigs there. Chinese banks still trade with Russians. Gold still flow thru international market from Moscow thru China thru India thru any buyers even if he is sitting next to Biden. Get a friend who lives in Moscow or any cities in Russia. They are not facing sanctions starvation. They actually having economic boom right now. Their supermarkets are actually fully stocked. While my local walmart store closing down due to thieving.
