I don't think Doge has any development now, so it's probably not because of some news... probably just classical pump & dump is being played by some PnD group. I personally wouldn't invest in Doge right now.
I agree, I would just dump it right now and take profits if I had bought some. Right now the best move is to do a SHORT on it since the price is pretty high and this likely would be a good short and take the profits out of the likely dump when the pump and dumbers stop pumping it. Likely they will also take a short position now that they have already profited.
