Buck. It's not xhash's fault.  The coins take 720 blocks to confirm and this current round of 720 has taken a few weeks.  Everybody is in the same boat.  In a day or so we will move to the next round of 720, the diff will drop and the whales and multipools will move in and 720 blocks will disappear in a few hours... Then everyone will sit back and wait for the painful process to repeat.
