Announcement: (2017-12-27 15:51 UTC) There is a recent surge of miners on XVG-x17. Unfortunately, this sudden overload caused the pool to mine on a diverged chain split. Upon reverting back to the main chain, the supposedly mined blocks have become orphans. Hence you will see a sudden drop in your unconfirmed balance orange line. Please understand that no one wants to see this happen. Both the pool and the miners lost money in this event. As compensation, pool will make fee 0% for the next 7 days.
