11$ per day is good but how much do you pay for electricity?
i suggest you to invest all your earning in alts because they have more potential to grow.
I pay 15.94p/kw this box is running at 375w currently, so 1000 / 15.94p = $0.01594 * 375 = 5.97p/day in electric cost. (if I'm correct.) although more then likely not. If anyone give me some clarity would be good!
