It's resistive heating that does something that most resistive heating doesn't do: generate some level of additional income in the form of cryptocurrency.

Only if you need full power heat 24/7 365. If you ever want to turn it off then it's costing you deprecation on very expensive hardware, vs a simple heating element.

Remember, few things need constant heat output 24/7 365, otherwise your going to want to generate some or all of your heat from other sources.

That's the brilliant part - doing it in Siberia where the heat is almost always welcome. Iceland might be good too.

Siberia gets warm in the summer as in it can hit 100+f, and you need a lot of insulation minimal heating even at 50f. So, not really.
