I got that 50 the first 2 hours mining and then it froze. My had rate was around 485kH/sec at the time. That's not the issue.
I'm just going to stop mining. Wasting my time and power bill is going up.
Are you sure your hash rate is 485kh/sec? At first I was also thinking my hashrate was around 200-300 kh/s and was expecting massive coins but wasn't getting any, than I realized it was hz/s no kh/s. The difficulty of this coin has gone very high and made it not feasible to mine with current hardware.
I did attempt to mine both with CPU (intel i& 3770k) and GPU (AMD r9 280x).
