You are getting $6-$7 per day at only 130w per card. $525 per card and $6 a day and lets say $0.1 kwh (im taking high electricity cost and only $6 a day) would mean you net 5.7 a day meaning you recover cost in less than 90 days (88 days)...
I would say fair deal.
Well that's a new tactic. You think you can price a card based on current price of a specific coin to mine? Who's to say it doesnt drop to nothing tomorrow? When people buy hardware its based on what its being sold for and retail value. Considering I paid $375 for my Vega 56's a few weeks ago I still have to say this is not a fair deal at all. Now maybe if in a month and there aren't any Vega's in sight and people are desperate enough then maybe it will be a deal, but right now? no.
