He is bitter because he can't afford KnC gear, although he claimed to have KnC gear and yet he is dissapointed in it and said it will not ROI.
Why all of the other KnC customers can ROI and he is the only one that can't.
If people calculate ROI as it should be - how much btc could I have bought for the price I paid for the mining gear. For me, 80BTC. Will I ever get that from my knc gear? No. So zero profits, not even making back what I paid.
And I'm certain any one of the 2000 - 5000 devices shipped after October 16th will not ROI, in those terms.
But yeah, I'm the only one who won't ROI. Whatever asshole. You are totally delusional and we'll see how clever you are when your neptune arrives in Q2/Q3

It sounds like you're just terrible at timing hardware purchases. I've got three Jupiters that have been hashing away for 6 weeks are have already earned back 80% of the BTC I paid for them. When miners are priced in USD, the price of BTC at the time of purchase is probably the most important factor in determining whether or not a purchase will be profitable.
Also, ordering from a great company like Knc that isn't trying to screw over miners also helps.
