could very well be he is selling his last 537Un on mintpal as we speak. We'll know later. Very possible more than one person was involved in the theft if you look at udNPskm7dR7viHsBE1XTjb6jF26676j8Lz

there is also the remote possibility this wallet could belong to someone who was able to withdraw later. So if this belongs to someone in the community please let me know so we can set the record straight.

edit: but i don't think that is the case since it was withdrawn in amounts of 49 (same as the transactions before that to the other wallet)
