that seems pretty low offer, considering these can do [email protected] (wall) underclocked with PSUs included I assume they are worth closer to $1200/ea
Yeah the general price right now is 75% of Bitmains pricing. So 3 BTC for 4 TH/s is fair.
So around $1200 is fair.
True enough but I hope you guys realize that difficulty is increasing at a good pace and that these are 0.60 to 0.69w gear as compared to bitmain's 0.25w. That is a huge difference in efficiency that can be had for just a few hundred dollars more. The other risk with these is the PSUs will kick the bucket eventually. I have SP31s and they require specialized and harder to source PSUs. What I'm saying is these represent a bigger long term risk than say S7s S5, SP20s, etc, and thus price has to reflect that and enough breathing room is necessary for the hope of ROI'ing. Perhaps my offer is a bit too low, perhaps not. To give you a comparison, I recently picked up a few Neptunes that perform at 3.0 to 3.4 for $700 a piece.
I must admit though that I am a bit partial to SP-Tech gear and I absolutely love their SP20 units
Having said that OP I can increase my offer to $750 + shipping.
