Bitcoin needs its own dedicated four dozen nuclear reactors with dedicated water supply. It doesn’t have that at present. Whatever its financial benefits, surely this is unsustainable: The current greenhouse gas emissions to support this rival that of many small countries, combined. Running at the intensity shown above for a single hour produces 6100 (metric) tonnes of CO2 at the electrical generating efficiencies the United States had in 2019, as reported by the U.S. EIA. That’s 54 million metric tonnes (“MMTs”) of CO2 per year. That works out to about 0.3% of a single ppm (*) of CO2 in atmosphere every year, just for Bitcoin mining!

(*) This is corrected for the fraction that persists in atmosphere, which is about 45% of the original quantity.
