maybe in their country there are many who mine bitcoin, the government bans botcoins for a while maybe this only lasts temporarily as long as electricity repairs run if electricity is normal then ban it and withdraw it again.
That may be true, but it needs to be seen whether the miners can recover from this extended period of closedown. Even if they are not allowed to operate, they need to take care of other expenses such as rent, maintenance and upkeep. For a while, they may be able to survive by selling their reserve coins. But eventually that will run out and they will be forced to make some tough decisions. One option would be to take a loan, which will be risky since we don't know whether or not the ban will be reimposed after 3 months. Another option is obviously to sell their mining rigs and make the exit.
