there is any gpu miner for this? an we be sure that there no private gpu miner dumping the value and killing the market? i see big miner with 21khs, when a cpu is doing only 500h, are they renting on amazon aws instance?
No GPU mining, there are no gpu mining going on, I have alot of computers with i7 and i5 running, so 21 khs is not crazy much.
Some people also mine on the same account, including me.
