I shut all my 1080s off once profits went under $1 per card after electricity.  Z9 minis are still doing nicely though.  Hopefully a big pump after a Bittrex listing for the ZCL/ANON fork makes the minis really profitable.  Kids (4) are all happy to have a nice gaming rig on every TV in the house though after re-purposing some of the mining cards.  No more fighting about playing PUBG, Fortnite and Minecraft now.
