Does this make sense to do?

• Spend about $7,000 to buy 10 Ryzen 9 7950X mining rig machines.
• At an electricity rate of 15 cents per kWh, the estimated monthly cost to run 10 optimized Ryzen 9 7950X mining rigs is approximately ~$130-$160/mo.
• 10 rigs running would produce approximately 75,000 BTU/hour of heat.
• Cold climate: About 125,000 to 150,000 BTUs per hour to heat my home during the coldest winter conditions, based on a rule of thumb of 50-60 BTUs per square foot for cold climates, (but the rigs would serve to cover the base load heat need for about 6 months).
• 10 rigs would generate about 210kh/s.
• According to Nanswap Nano Mining, this would indirectly mine ~200 XNO /month at current exchange rates.
• End result, I heat my home with CPUs and get ~1,200 XNO out of it in the end of each winter and may lower my monthly energy bill on a net basis.
• I wouldn’t go any any bigger than that since I want to be environmentally friendly, but I need to pay for the BTUs anyway to heat my home.

Can you create a “business” out of this and write off all the expenses too?

Is this a good idea or bad and ultimately just a tremendous waste of resources? The thing is, heating the house is an essential burn that has to happen one way or another. Seems like doing it this way would bring the heating cost to near zero, or maybe make a profit even. I am trying to figure out and really think this through. What am I missing?
