So far, I do not see any particular problem with Russia's payments for its oil and gas supplies to other countries. The geography and volumes of such deliveries are now changing a lot. The countries of Europe are gradually refusing energy carriers from Russia, a partial embargo on their supplies is being introduced to other countries, and to others Russia has the opportunity to accept the usual currency. The problem with payments for oil and gas in cryptocurrency is not relevant for Russia, since not only money is tracked, but, first of all, the goods themselves, the movement of which in such a large amount cannot be invisible to other states.
