Russia should start to embrace bitcoin and other crypto currencies if it wants to regain it's status as a super power. It has lost the cold war and the economic wars, the only way to win the next one is to start stockpiling and mining crypto
I don't think crypto or Bitcoin can save their economic situation. Because the cryptocurrency market is still quite small and it still has no strong impact on Russia's economy.
In order to revive their declining economy, I think Putin should re-establish taxes and some reasonable fiscal policies over the next 5 years.
