D3 sounds great deal $1599
availability is the issue
D3 being difficult to get won't make Baikal miners profitable. It's still a waste of money above maybe $1k max.
Well I will not be mining DASH or DGB or Nicehash. I'll be mining my secret coin and I have 2KWH max of electricity free and included in my Rent. So I have no issue for ROI. And I know I can mine with these miners for at least 2 years with different algos and coins. I am a Horder.
There's not much outside of X11 to mine. Most of the coins on those other algos are dead.
