I got it off ebay from seller "secondhandgpus". Sounded like it was from a mining operation in Quebec that folded, or was liquidating stock. $1,046 Canadian including shipping. But yes, multi year cost recovery. I can run it as heat from Mid October - Mid April - so about 6 months. Call it $4.50 Canadian/day so make $800 or so for the 6 months at current BTC prices. Maybe we get a BTC price bump so MIGHT break even after two years. However - we wanted to buy a heat pump or some other forced air style heating system anyway which is MUCH more expensive to set up. Easily 4 x more expensive if you go high end. Probably cheaper to run, but my thought was the extra cost savings which I keep in Bitcoin have a chance of appreciating over the next decade. Tough to weigh all the options and potential outcomes.

All said, I'm confident this was the right choice from a long term financial view point. We might have been better off in 10 years just leaving the baseboards and keeping the $2000 in BTC - but it's quite amazing the difference forced air over radiant heat is making. It's worth whatever that ends up costing.
