Pretty sure they’re already mining, probably using the Chinese pools.
If the US pass that 30% electricity tax for mining, they essentially push the miners to leave.

Russia is the second largest home to hash rate behind the US and their government is now in a public-private partnership with a mining company in Siberia.
Which pools do Russian miners use?
Not sure about pools, this link is a Russian news outlet that a ton of “crypto” publications (coindesk, btctimes, etc) were citing to after Q1 this year. https://www.kommersant.ru/doc/5915688
