I think this quick dip and spike was more a result of computer trading and not really emotion. They are programmed to sell on any "shock news" no matter the asset or content of the actual news itself (would have looked the same for the stock market had it been open). The quick recovery is then the opposite more rationale reaction as in "Meh,it doesn't really matter in the end "

Doesn't change the fact that bitcoin is a 24/7 pulsemeter to the news though.
