Will sale offshore for like 3 weeks.
Considering what to do with the rigs...
Just leave it,hard reboot once a day or once a hour...
Is there any real good software that can check if miners are ok and all the cards online?
Some pools send an email if your rig goes offline. I also add a 4 hour restart loop to my nvidia rigs. Lose maybe 0.5% of profit from that restart, but there's no need to worry if something hangs.
