Dash is a stable coin that has never actually been unprofitable with a D3 (unless your electricity is prohibitively expensive, like USD.35/kwh or higher), the profits are just super low at the moment. However Dash's value does continue to climb, so unless you are cashing out daily your profits/ROI/etc aren't quite so cut and dry as the numbers on whattomine or anything. In the past month, the value of DASH has doubled, and a steeper climb if you go further back than that.
I personally think 2018 is going to bring a lot of momentum to DASH--there are movements to create POS systems for medical marijuana sales in the US utilizing DASH to circumvent the current bank problem the industry experiencing, for one--so even though my ROI point is still months away mining primarily DASH, I'm sticking with it. But yes, if you are selling regularly, it is not a very profitable coin, but it is still profitable...

They seem to have a lot of X11 coins.
I will be getting my D3's soon, I honestly have no idea where to point them....
I use Spurnova for my D3. It's pretty good. Remember it is PPLNS, so don't freak out if your first day isn't as fruitful as you expect it to be...
