No one can mine at the moment with BAIKAL X10 as their hardware failures in the tests.
So by watching nicehash you can dream $40 / day with Baikal X10
Wait till BAIKAL will resolve the problem and you will see the real profitability

Be clever and use your brain !
I have three mini miner, four cube.... all working fine.... i bought the first mini in February and now is still profitable... ( after 9 months small profit but is profit)
I Bought 3 D3 Bitmain First batch..... after 50 Days i say 3 things.... frequent disconnection.... impossibile roi..... some hardware error.....
The future of x10? I don't know but worst than D3 is impossibile.....
I for one can't argue with what you've said.
