I think the information that will (hopefully) come out over the next few months about MtGox may require much of what we think about the history of Bitcoin to be re-written. MtGox has been instrumental in many of the major price moves in the past few years, and it may turn out that those moves were not simply market driven, but were as a result of internal manipulation.
Of course this could all be a bit Tinfoil Hat, but I think there is certainly a significant probability that the Willy bot, the timing of the DDOS's and  Transaction Malleability has more it's the story than we currently know.
