I'll give you $50 bucks tops. Not half a btc.
Some of you have invested millions of dollars in equipment. A +$0.6 software boost per card could save the farm when the market is crashing. For the smaller miner my renesis miner 2% fee + 0.05 BTC is a good option. It's a gamble, but a gamble can sometimes be very profitable...
It's downright retarded and you're taking advantage of retards, that's not at all politically correct.
You can resell hardware, are you saying they should resell your miner to ROI?
