Hi I was using this site for a week or so.
The first 2 days I was getting 0.01 BTC from a 730 KH/s GPU.
Then when the BTC went up it was down by half to 0.005 per day.
I stooped mining there and went to mine in Dogecoin.
For now it is the most profitable coin to mine I know.
Does anyone think otherwise?

try https://www.multipool.us
It mine the most profitable coin Automatically for you and then you can exchange them on cryptsy.
Good Luck!
