Anyhow, a 5-7% decrease would match my expectation if we take into consideration the increase in BCH price, thus migration of hashing power and nothing major coming back online. There still could be the possibility of bitmain decoupling s9s and brining s15 online but...I doubt they would do it this way, and not try to keep as much hashing power online all the time.
A jump by late November?
My guess is still flat or close to flat the need to move upwards in diff is held back by a lot of factors.
A few years ago when I ran the diff contests thread. " heinz57 " can't remember his name came up with the idea of hash spike showing future numbers. I coined a clever name for it but it was his idea.
High spike in chart below shows network to be over 57,000,000,000 gh
not the current number of
Hashrate(?): 46,724,750,622 GH/s
So this spike could mean we move to 57,000,000,000 in under 2 months.
with bitmain's new killer machine maybe so. time will tell
but the break from august 24th to Nov 15 will have been nice.
