Picture a basement in January where the space heater is a Bitcoin mining machine. Almost all the power it uses comes out as heat the family was going to pay for anyway.
The strongest critique of mining: big operators with cheap long power contracts and first pick of machines make "anyone can take part" close to fiction. On scale I think that is mostly right.
My claim is narrower. Power bills get paid in dollars and machines wear out, so miners sell part of the roughly 450 new coins a day. And whoever has the cheapest reason to run a machine keeps showing up, a dam or a cold basement.
I would change my mind if home and small operators keep shrinking across several four year cycles, heat reuse included.
What does your winter heat cost you per month?
