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
This is incorrect. The ebang ebit has already been delivered, it's using 10nm chips from Samsung, but it's still only an 18T/Hs machine for around 5k USD, so it's not really the game changer I expected it to be.
Those are mostly just marketing BS. In terms of energy, the ebang machine is using .09J/GH +/- 10%. Which is only a %10 improvement over S9s. So the improvement is within their margin of error.
But even if we give them the benefit of the doubt. When you solve the equations for the ebang machine, at an optimistic rate, it will only earn 0.45BTC during its entire lifetime. (As oppposed to S9s 0.37BTC). That is the entire lifetime of the machine. Assuming the machine is operating with free electricity and is running until end of time. In reality the lifetime earning will be much less.

Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
since bitmain opened the last batch it hasnt sold out... either they have increased production by a lot, or there is some backroom information that the big companies arent buying any letting the small ones take the hit, considering there are news about smaller chips and samsung coming to the game and a lot of people with big farms selling all their S9's; brings me some fear (since i got a order open for march) that they are either coming with a new miner or some other big news is coming out, anyone else with these thoughts ?
I just signed up to post this here. I think the math doesn't add up anymore for 16nm chips. Unless you are doing liquid cooling and even that is almost breakeven.
