1000kh/s = 8750USDe/day
This is not true. I only get a little more than 10k USDe/day with 2500kh/s on steadyminer..
This made me do math.
On the other hand, mining on my p2pool server netted me 31,512 in the last ~24 hours with ~1.8mh/s. But it was a lucky day.
If you have a spare pc, I strongly suggest running one, or finding one near you.
