I mine with 1KH/s for moneropool.com. The estimated mining profit should be about 0.12 XMR/day, but I'm getting much lower profits, only about 0.04 XMR/day.
The site says that on average every 40 minutes a block is found, but I often see that the last found block was 3 or 4 hours ago.
So, whats wrong here?
