And the exploitation of Bitcoin has become a tool to rescue the people of the country because they can take advantage of low electricity prices to exploit.
Also I've heard of cases in which police randomly decides to confiscate mining rigs, claiming that electricity costs are being subsidized not to mine or take advantage of it, but to instead buy other products of first need. So in terms of government, this could be said that is 'illegal'; same way as if in another country you steal electricity to power you own rigs.
