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.
Hopefully more people will adapt to asic-resistant coins til then. Scrypt is almost dead for us GPU-miners.
