Payback or ROI for d3 is about 10 days...i found it on cryptocompare website...
With a current coefficient of difficulty (which promoters always "forget" about in their product releases) yes, but you do not have that ASIC in your hands right now, do you? By the time you get it up and running the ROI time will be half a year and rising fast day after day, and in a month from the date you receive it ROI time may rise to a year and keep rising (unless you get lucky, and the price of the altcoin you will be mining will skyrocket)... Gamble, but do not put everything you have on red...
