I suspect the 1.3% difficulty increase per day may not be sustainable... Anyone have any thoughts on this?
I have a question about the Coinish's calculator... Does the Income after reduction include Break even or is it the income after you break even??? I would think ROI would be the amount you make AFTER you break even and pay off your Miner? It has to be or else there is no point to buying any miners unless you can afford to get like 100 of them? Something is not adding up..
The cornish ROI calculation on Expert mode is Income over the planned time minus investment, power and pool fee's.
