prolly 400 watts running all day...so if your electricity is lets say $0.15 per kilowatt...be like $0.05 - $0.06 per day.

you can lotto mine it for an extremely unlikely chance of a block, or point it to like braiins, lincoin, or Ocean and get paid out a few sats via lightning (youll never meet any pool thresholds for on chain payouts). you wont recoup the cost but considering how unlikely hitting a solo block is (my bitaxe currently has a solo block likelihood of finding a block once every 30,000 years), id point it to a pool 🤙
