OP too stupid to realize bitcoin halving in less than 32 days. He prolly knows nothing about dff jumping up due to S9 release. Well, the ignorant will inherit the hell.
Yeah...obviously it would have been at least 2.5x better to buy s9 units, way less power draw, heating required, space and noise reduction. Halving right around the corner with probably a huge spike in difficulty. I would not have the balls to risk 100 s7 PLUS 100 psu's with all those conditions. Screw that. Even with the extremely low power rates.
