I been mining on supernova since 27th and I have been out of town and I only managed to get like 1.3 coins. and since I came back today at supernova I have gotten 0 coins and my hash rate in over 6000 kh/s anybody know whats going on?
Less hash rate. This can be sorted out only when more people decide to neutralize the monopoly created on 1 pool (MPH). Besides that, suprnova had some issues which were promptly fixed by zcoin devs. Now the pool just needs move hash rate to improve the earnings.
At present the hash rate is like MPH hash rate > hash rate of all other xzc pools combined together

And an advice to all other pools like suprnova, zpool, etc. Make an attractive offer (at least for the time being). Something like 0% fee till the traffic increases to a level that can maintain hash rate balance between pools.
