If I were you I would stick to the third option.Keep using your cards even at a loss and hope for a better day to come.If we dont believe that a better day with a better coin price will become then we have to ask ourselves what we are doing in the crypto zone.
Running miners or not has nothing to do with believing. I let the system run already a few months with overcost. But at some point you can't justify to through anymore money out of the window. Because why overpay for crypto if you can just buy it cheap on a exchange?
I'm trying currently option 2, did 1 just for fun and as expected no stupid people around. Had only offers from pros and they were lowballing me (rightly so). Option 3 would be just waiting, but still miners would stay offline ;-)
oh man, familiar story, so many of us smaller miners hit the crossroads in the last year i think : /
me personally i didnt have any luck selling as rigs or just the GPUs, i had to build my rigs into desktop PCs to sell them whole to non miners
was the only way

i also ended up taking massive low prices on most equipment (of course)
but these rigs ROI'd like 4x atleast over the years i had them so no big deal there really, was all profit at that point
i ran my rigs at home at a loss for a while, but eventually ya, you just cant shell out of pocket anymore nope
you? if you cant host them somehow (shipping them here to Canada for cheap hosting for example might be way too expensive in itself) then damn, take w.e u can get i guess for sales as mining isnt gonna go backwards anytime soon and make old gpus profitable again (like it used to), its too commercialized now
