Captain Obvious here again:
The price increase was due to one or more entities simply purchasing BTC, they were not pumping the price as we normally see, they were accumulating all in one go; The reason the price faltered afterward.
Yeah, right.... That's great logic, and this one entity chose to make such a purchase during a very low volume time in order that they wouldn't have to pay the same price for every single coin.
Edit: Looks like Blunderer beat me to the punch on this theme..... funny that I may have been reading this thread so long that I am beginning to parrot some of the ideas of Lambie...
