So are you telling me that all this hashrate is mainly from the chinese manufacturers? I find it REALLY HARD TO BELIEVE IT considering that the S7 is on the market for over 5 months now and the exchange rate is bigger than 250$ for over 3 months now. Why would anyone buy miners who were present on the market for such a long time now instead of 3 months ago? The network has added 200PH/s in just one month. You would have to be ultra retard to invest such a big amount of money for an old generation of miners when your chips were knocking on the door. You and 21Inc are the only ones that are capable of deploying such massive farms. I simply don't buy what you said, but it's understandable from your position
