Russian is so well known for its mining industry. As far as I know, mining is not banned in Russia, since people are still engaging in mining activities.
Anyway, put it on the legal lever may be beneficial for those big miners, expecially those close to the government.
Well Rusian contribute about 11.2% to Bitcoin's hash rate and mining in Russia have not been affected entirely but about 2 mining company have close down operation so far and have stated that the shutdown is connected to Russian Ukraine invasion. This situation may change as things progress bit to which direction I can't tell let keep observing to see how the whole situation unfold.
