And there is also no evidence, and no basis for the assumption that he moved the coins to "embezzle" them.

In my opinion, it's just as likely that he was moving them for "security" reasons as it is that he was doing it to "steal" them. I haven't really seen any real proof to say either way. The only thing that can be stated for a fact regarding the movement of these coins, is that the coins were moved... and the only person that truly knows why this happened is Hhampuz (assuming Hhampuz is the only one with access to the private keys).
