Sincerely I am not interested in a ROI or to balance the cost of electricity with the earning sats. I am more interested in warming my wife feet 😂😂😂 so she can shut up, meanwhile I am paying the same money for heating I am paying now.

As far I can see and calculated, I would pay around 10k-12k sats/month just to warm wife feet. So with a 4T hash rate I could make like 7-8k sats/month. It means I still have to put from my own pocket 2-5k sats/mo.

Keeping in mind that right now I am paying the same 10-12k sats/mo but nothing in return.

Am I right with my assumptions?
