Certainly the feedback loop has caught up to people? I mean, who is ordering from cointerra? Who thinks there is any chance of a btc profit there? We have the required feedback to know it's a bad idea, yet their hardware will continue to be produced.
What about people paying $7000 for a Jupiter? The feedback is all over the place yet I guess people are still ordering, but at this point, even if people don't order, that hardware will get used.
In theory, at least, that should keep KNC (and other producers) honest. They make their best guess how much a Jupiter will earn mining, let's say 50 btc. If they price it at 100btc, no one buys it and they're left mining with it, receiving only 50btc. If they price it at 55btc, it's more likely to be sold and beating KNC's own estimate of what they'd earn if it doesn't sell.
Unfortunately there are a lot of greedy and foolish people out there willing to overpay, and if KNC counts on this, it distorts the prices.
