On the white paper it shows 20% of income going to service and Electricity, it would be hard to have exactly 20% on expenses. What happens if there are more or less expenses than that? Where will the money come from/go? I feel like the 20% reinvest might be a bit low also, as you have to compete with the 10% to 15% increase in difficulty each month. If the difficulty starts catching up with the money put in things can go downhill quickly.

Would be better to have something like

Income - services = profit

Then profit share:
50% ROCK2 owners
40% reinvest
10% mining team

Other than that it looks like a solid project
