Might this show that some long term holders foresaw the withdrawl suspension at gox (and resulting price corrections across the exhanges) and elected to move their coins to safer harbors?

BDD is weighted toward coins that havent moved in some time, so the implication is that it was old money. Then again, combined exchange volume seems to be 4x what is has been over the last week or so, so maybe large numbers of weak hands panicing?
