so if Russia manages to make mining legal now, miners can now freely mine crypto without hiding, while the government benefits in return through taxes and every other kind of fees miners would be expected to pay, this could at least help their economy, even if personally i think the effect would be minimal.
I also heard, after a lot of sanctions received, they started to retaliate in a way "they will only accept GAS payments using crypto(bitcoin)" I don't know if this is just a plan, but one thing I do know is that as long as the sanctions last, I think Russia is going to be very crypto friendly. they will solve the country's economic problems by using crypto.
this is due to the ruble in free fall, due to the swift ban which makes it even more worthless. but with the existence of cryptocurrencies, it can replace the ruble to make transactions, because crypto has one price throughout the world, so this does not prevent Russia from developing its economic sector. many countries do not yet have regulations on crypto, and this is a gap to replace the ruble which is the country's official currency
