We should also keep in mind that Russia has lots of experts in Math, Cyber Security and Cryptography due to their education system. I still do't think Russia would make a sudden and immediate venture into BTC as the network is completely unable to handle scaling properly. It would end up being another coin that is more scalable. They might also be thinking about stability of the coin.

Individual investors on the other hand may start slowly putting in their money. Some time ago I saw an article about even Russian criminals getting into crypto mining. So there are undoubtedly good signs.
