I think mining is considered passive income. Unless you got some mega farm where you need to monitor 24 hours a day then the original setup might take a few days weeks to sort out but as long as your rigs aren't crashing, you are pretty much doing nothing to make that money.

Once in a while you might need to reboot some rigs or change some part like a riser or PSU. However you are pretty much making money in your sleep. This is passive income. Sure its possible it might not be profitable in the future, but you just turn off your rigs and wait. If it doesn't improve just sell all your gear and move on to something else.
