Even if it was true the first time the claim was made, that doesn't mean it's true today. It's the same deception made about IC cars being dirty. Their exhaust may be dirtier compared to that of an EV, but it's 99% cleaner than the exhaust of an IC car from 1990.
Just as progress has been made in making exhaust for IC cars cleaner to the point of being trivial, much progress has been made to make crypto mining more green and energy efficient.
Incentives matter.
