ROI to the moon! 
I´m not really sure why everyone is bashing the D3's so hard.
Do the math.
Lets say you've paid $1500 for the D3.
Profitability today (according to whattomine.com) is about $13 daily if you get the 19.3Mh/s version.
Lets assume that the profitability will be reduced with 20% montly.
This gives you a ROI of about 6-7 months.
Its really not that bad.
And what if everyone is wrong and the profitability stays up and reduces with lets say 15% montly, that will give you a ROI in 5 month +a couple of days. 10% = ROI in 4.5 months.
This is of course a very simplified calculation, but it gives you an idea.
In my opinion, the D3 is not as bad as people make it sound.
Now it's 9.33 $ (17Gh / s) every day. And I'll tell you that it will be a disaster ... Bitmain sold in the beginning of November 40,000 units, so that the guys bought very expensive heaters.
First of all you have no idea how many they sold. Second, I remember when the S9 was barely making 5$/day. If you're in this to get rich overnight, then you're a moron and deserve to get burned.
Firstly, if you do not know this does not mean that others do not know. Prior to updating the site, the "Remain" line was written in the page code.
Secondly, everything goes to $ 5 per day but only here Dash will hardly cost $ 2000- $ 7000 or more
