In this regard, it is possible to speculate a scenario in which the miners continue to develop their work (those who accept), but the bitcoins of the rewards go to wallets controlled by the government. In theory, the authorities would receive the funds, deduct taxes, distribute the rewards and encourage activity in the country.
This makes absolute no sense, because government cannot really control miners.
A mining pool may be based in Russia, but the hashing power may come from somewhere else.
In the end, even if the goverment could effectively track mining pools and miners, miners would just move their operations to a more free country. Or just move their hashing power to a pool based somewhere else.
