You pay 60$ a chip, they pay 1$. They will push as many GH/sec as they can as fast as they can and mine themselves. For them, these chips pay themselves back measured in hours.
If anyone is dumb enough to buy their chips, they will put out several dozen for every one you buy, funded entirely by you.
Scrypt is dead.
Scrypt on GPUs is only dead when the hashrate on network surpasses by a long shot the # and valuation of shitcoins generated, marketed and entering exchanges every single day.
I've been mining memorycoin which isn't scrypt for a few days though. In the best days, I got 3x the profit and the GPUs use ~60W each instead of 150
