As i posted in another thread - assuming that each titan does 250mhs @ 10k and a Gridseed (minimum) 350khs minimum - each Gridseed would have to drop to $14-16 to match that type of khs/cost ratio. I highly doubt they can be sold at that amount for profit.

Glad i stuck to my GPUs.  When Gridseeds are worthless, my GPUs won't be.
