I'm conflicted as well. On one hand I do mine (with my gaming PCs, I don't have a dedicated 6 GPU rig or anything like that) so the $7/day at the present rate is less than half of what I pulled in earlier in the year. On the other hand, the GPU scarcity and subsequent gouging needs to stop if PC gaming is going to continue as my primary hobby.
And this, friends, is how you mine. Sensibly. You use the stuff you already have, and you watch the electricity bill to see if its worth putting your rig through the stress of maybe having some free wampum.
Kudos to YOU, level-headed Sir.
