I don't think it can.  this is a pump and dump.  watch the buy and sell orders. thousands of sell orders along with hundreds of small buy orders 1 satoshi higher than the going rate.  I think someone found a way to trick the autoselling multipools with well placed buy orders forcing the autosells to go up.  If someone wanted to buy a lot of doge they wouldn't be buying at higher prices and low volume they would put in 1 big order and get as many as they can.  there is no way we can sustain this level with near 50,000 more block until the reward halving.

hashcows and multipool are both still mining doge and with the price increase they are not going away anytime soon.
