Doge is just a dodgy bitcoin clone, any vulnerability in bitcoin will be in Doge. Think of it this way - it wouldn't kill you to sell just a bit of your Doge, maybe 20%. Then if it drops you can buy back more for the same money, and if it rockets you'll still profit of the coins you kept. Split the risk. And for the record I don't hold Doge, I hold other stuff and I've been selling off drips and drabs of that just in case.
