Phill, we seem to be on the same line, the majority of people, however, would think the opposite...
I also think the same. I think this rise in diff is caused by S9 s turned on when BTC price went up but i think this can end soon and BT price will continue to rise but diff will stop for some time. No way Bitmain and other manufacturers sold many of new model miners - their ROI was terrible and it still does not look too good.
