So from the replies it seems the only way to get a ROI% is to dump the hardware on some unsuspecting person while you know they will end up losing money? That is extremely selfish, bad karma, and I will pass.
no, you sell for a fair price.
and for people that don't believe in karma, your second point is irrelevant.
You should be able to get a ROI by mining coins, not ripping someone else off so that you get profit. You guys that said this are what is wrong with the crypto world today.
to get ROI, do your homework.
you seem to think you can simply buy a box, make money from it, and not do any research of your own.
The only fucking research you should have to do is what coin to mine, not making someone think they are getting a "fair price" while in reality you know you are ripping them off. I know about mining coins dude. I spent over $5k on my GPU set-up and have already paid that off. The hardware still retains value as well.
