Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
I'm feeling like there should to come new "S9", like there was jump from S7 to S9...4th > 13-14TH... S9 is becoming obsolete..Unless you have free electricity...Or Bitcoin jumps...But you can't just wait for it to jump...Difficulty is increasing enormous speed...And new Dragonmint...is ONLY 2TH better then S9...We need crazy jump in tech again 
There won't be a big jump anytime soon. The reason we had a big jump form S7 to S9 was that S7 was using 28nm chipset in 2015. And in 2015 we already had commercial production of even up to 14nm. But right now S9 is using 16nm which is pretty much the bottleneck. The next step is 10nm and that is barely getting into commercial production today and when it does the foundries will be booked by giants like Apple and Samsung for some time. So S9 is here to stay for at-least another year or two.
you can increase the hashrate by liquid cooling, better design, etc etc. But won't be anything like the S7 to S9
