as far as I know, Russia has not yet adopted the necessary laws to allow cryptocurrency to move freely, but as a circumvention of sanctions, cryptocurrency could help, but judging by the news they do not have it in the first place and I think the cryptocurrency will be in limbo.
Days back to the war the bill for the legalizing of bitcoin was taken into the parliament discussion. Even though legality is positive, it can't make an immediate change in the market. If people have got time there is possible chances of massive adoption and people holding good volume of cryptocurrencies. Now people are willing to make an investment, but they weren't able to do it. Because, the entire banking system is shut and it is difficult to transfer fiat and receive bitcoin.
We are talking about whether the cryptocurrency will save the Russian Federation as a state from international sanctions. If we consider from this side, then we must say that no, it will not save. Including the citizens of Russia who fell under these sanctions. The fact is that not only transactions are tracked, but also the movement of goods. If Russia is prohibited from supplying certain types of goods, then all participants in such a transaction will become aware of their supply for any currency, including cryptocurrency, and they will also face sanctions. Therefore, now that there is not even an embargo on Russian energy resources, even China does not really want to buy oil and gas from Russia, so as not to damage its image. Putin's Russia is rapidly becoming a pariah. And this is just the beginning.
Recently there was information that the Russian propagandist Solovyov, who was under sanctions, had two villas confiscated in Italy. What difference does it make for what currency or cryptocurrency he bought them for. The sanctions are working.
