Kind of true, but is it widely used form of producing heat? From where I live, the heater burn gas from PG&E. So it is still doing the inefficient kind of turning energy into pure heat. I’m still undecided on the subject (whether crypto-currency is intrinsically bad to the environment or not.) Eg what if we regulate and only allows renewable energy to perform this. The basic argument is to intercept energy which would have been turned into heat anyway (solar, geothermal, etc.) and instead directly turned into heat, perform mining first then to heat. For others who may misunderstand, they are talking about thermodynamics. Ie the amount of heat produced can be higher than the energy you put it, because it also get some from the environment.
