One year ago Bitcoin's network was consuming as much energy as Ireland. Now it has apparently doubled and now it is consuming 1% of the world's total electricity consumption.

Is Bitcoin sustainable as it is?
I don't think so - in fact I'm sure it is not. There is a limit to insanity.

I believe that it would be possible to consider the heat energy that miners produce and direct it in the right direction, for example, for heating residential buildings. Thus, mining would become one of the few sources of heat, along with a heat station that spends electricity or fuel on heat. And consume electricity and they are too many, and even cause harm to the environment with their emissions.
