I dislike Bitcoin because it's fundamentally flawed and wastes enormous amounts of electricity, but I do like blockchain and distributed ledger...
Hard to ignore the price of Bitcoin these days though. That got me to thinking (I'm pretty slow), I have powerful hardware laying around, I've banked excess electricity from solar, and this is the heating season...
I finally figured out how to find how much excess electricity I've banked. It's at the bottom of my $12 bill ($11 for the connection, and $1 taxes). 800 kWh.
I don't know how much electricity the mining rig would consume, but it has dual 1600 watt power supplies requiring 240v. If I pulled 1000 watts continuously, I could mine for a month using my banked solar credit. 2 months if it only pulls 500 watts.
As a bonus, I'd run the gas furnace less during the ~6 month heating season.
Here's a similar setup to what I've got to work with, only 1 GPU instead of 2. I think it can take up to 3.
