Well, you know those people who caused the crash purposely (and were there trying to make it crash even further as explained in that crash video lolz) accumulated many millions of $ selling their BTC like crazy there at the end when they hit the 6000$ wall - I'd guess now that they were just buying back in shamefully, having been soundly defeated in that massive financial war that happened and that most didn't realize was going on... Perhaps the first massively public round of the war for the future of finances and who controls the world, between the old rich and the crypto rich.
