Here are my earnings for the last 10 days
Giving an average of BTC0.0134 per day
This is on 800ish Kh/s spread over 3 cards & 3 virtualised CPU machines (I know!)
Yesterday was made worse by me spending some time tuning my card performances & I crashed one of the machines with 400Kh/s for about 4 hours.
Good information as I have similar (~850kh/sec) hashrate pointed at middlecoin. 0.0173 BTC/day average over those same 10 days.
