Sanctions are definitely the reason for this. Normally Putin is a dictator, so that means he would not want something as decentralized as Bitcoin to exist in his nation and would prefer to ban it, but even if not ban it, regulate it heavily. But considering western nations are focusing on sanctions, that means not only Russians are having trouble selling their stuff and using anything else for payment, and also there are many oligarchs who are rich enough that they want to bring their money back, to avoid sanctions and asset freeze. So that is why I think its clear that we are seeing Russia putting crypto in a good light for them.
