I'm convinced the people here "worrying" about difficulty levels rising and "suggesting" people do anything OTHER than order a D3 are just fudding and in reality want all the D3's for themselves. Right now, these units have a 9 day ROI. even if earnings drop 4x you're still looking at ROI under 1 single month. Yes customs and bitmain website and order process are huge pains in the ass, but if you can get through it you're gonna do very well. don't listen to the people crowing about difficulty. When difficulty goes up, generally the value of the underlying coin goes up - JUST LIKE DASH IS EXPERIENCING RIGHT NOW. even though difficulty goes up, profitability does not proportionally decline.

anyway i got 14.

by the way, if you're serious about mining, you need to check out the gigawatt white paper and the WTT token.
