The resell value may not be good however.
Yeah that is one of the great cards for mining but unfortunately its price it is not that low right now,I see in Ebay with price being 180-200 dollars and I do not consider that a cheap price for a card which is some years old now.Where I live I can easily get the 3060 ti which is a bit better for 120 dollars right now.For people mining now this is a good time to stock on such cards and build a good mining rig with 12 such cards for just 2000 dollars as that in ETC+ZIL can make you a considerable amount of crypto monthly,of course we do not talk about profit but for good amount of crypto which in the next bull run may prove the best investment one can make.

I would definitely advise you to choose other mining equipment for this coin instead of video cards. It will be both cheaper and more profitable

Bitmain Antminer E9 Pro in a noisebox will be a good choice, if you do not take into account the risks of failure of 1 ASIC.
