Hello everyone I'm close to pulling the trigger and pre-ordering an antminer D3 and it would be for the December batch. I'm nervous that mining profitability will drop a ton by the time I'd receive the D3 and I'd be stuck not being able to reach ROI. Currently Dash is around $4k a month profit with the D3 after power costs.

With the increasing difficulty due to more D3s coming online how much should I expect profitability to drop by 2018?

I do realize it can mine other coins as well with the X11 algorithm so that may be an option if Dash isn't profitable anymore.
