Where I live the connection fee is $20/mo and bi monthly bills are anywhere from $100 to $1900, we have electric heat in and older house

Electric baseboard heat with minimal insulation?

A heat pump is much more efficient than electric baseboard heat, you might as well run your computer to generate heat since it is equally as efficient as electric baseboard heat or space heaters.

Idea: sell space heaters that secretly are bitcoin mining rigs.

Funnily enough it's been done:

If only we could have the heater PCs do something actually useful.

Imagine showing this real product to yourself 15 years ago.

And imagine actually using one of these. Space heaters are one of the leading causes of fires, these ones seem like they have much greater fire risk since the Bitcoin stuff adds complexity that regular space heaters dont have.

Lots of insulation but probably crappy tenants leaving windows open. Also it is -20 outside.
