If it's true that Bitcoin mining is concentrated in these regions with cheap coal-fired electricity, there does seem to be a fairly direct linkage from coal-mining to coal-fired power plants to Bitcoin miners without too much of a reach. If Bitcoin mining is using 0.5% of the world's electricity output (a frankly astonishing number) and mining is concentrated in Xinjiang, then what percentage of Xinjiang's electricity usage is going to mining?
