I think you are alone on this boat or with very few people in it. Why the price should go sub 600 in the first place ? There's no reason for such thing especially now that S9 Antminers are coming into the market which will add the price up as bitcoin mining will be profitable in the few months post the production of S9 Antminers. I am in a new boat. The one with 800+ price after the few months where S9 Antminers will be profitable and the volume will be high in the trading. In fact it already is.
