Re: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order
...Sure, go ahead and pick up 'my' unit. It is sold..to you, personally.
With a turnaround time under 230 days, I thank you and I grabbed 9 more after yours. 
You probably base it off some overly optimistic numbers..
$1410 cost
1350 watts at the wall (1225+10%)
current 7.81% difficulty rise per adjustment period.
NO brake even, EVER even at zero electricity cost if difficulty rise continues like this and btc does not appreciate.
Check for yourself.
However, if difficulty is more reasonable 4% and cost of electricity is 5c/kwh, then only $178 loss by the day 376.
If electricity 3c/kwh, then breakeven by day 341.
Show your real numbers...Or not, since my electricity cost is much higher than 3-5c, which was my initial point anyway.
Biodom, the flaw in your calculations is that you are forecasting a difficulty rise but not a BTC price increase. If the BTC price holds flat, the difficulty rise will not be 4% on average. You have to also assume a average % increase in price if you are going to assume an average increase in difficulty.
Nice try on convincing the mining market to wait tho
