For me this marks the end of mining as KNC was my last hope for providing miners with a positive BTC ROI but it appears they too have succumb to the greed just like all the others who have found themselves in this position. I really was starting to buy into the idea that KNC was going to bring us early customers along for the ride but it's now obvious they've taken the ball and gone home without us...
I'm not done mining quite yet. I'll keep all of my existing preorders, really just because I want to geek out on them. But I'm done buying any new mining gear, preorder or in-hand. I will continue to let my current gear run until they become unprofitable and then unplug them. And then I'm done.
