Wow.. Look at all the mouthly little yips with under 50 posts demanding answers.  I can clearly see why you were using nicehash.  You have no social interaction skills or common sense.  Offer suggestions and realize that someone could be in a different timezone on the other side of the world.  Sleep comes to us all, unforseen issues come to us all.  If you don't like things leave.  If you want to give things a chance, stay and shut up and observe.  I've been with this pool for years and as hashrate grew suddenly we had some hickups.  This hasn't changed but over time he has expanded to make things smoother.  Who sees 4700 BTC disappear suddenly?  As for comments mining in the dark?  What do you think nicehash was doing?  Your hashrate is calculated by the shares you send not your overall hashrate on your side.  Completely different system vs nicehash which is PPLS against PPLNS which is zpool.  If you don't know what those are I suggest either reading up on it or sit down and enjoy the ride.
