I wouldn't necessarily accuse them of cheating/stealing, I think it has more to do with incompetence and a terrible pool software.
But yeah, I was mining on two pools at the same time and from nicehash's pool I got like 1/7th of what I should have gotten if I stayed on the other pool (coinmine) even with the slower miner (0.2a).
Probably right.. but really incompetent and poor software.. He did pay out finally at .003 so I got some funds. But making way more at Suprnova in just 8 hours. In about 12 hours I have made well over .002 in what took me over 24 hours to get to that .003. It would not been so bad if he would of been responding to the forum threads instead of ignoring his pool threads.. Letting people know if he was going to fix it. If he would lower the payout or anything he/she was just being hush hush which really looks bad.
