that is a very strange move by the hacker! there are already many ways to exchange coins with each other and there is also mixing techniques that could be used to make it harder and even impossible to trace the coins! i am wondering why someone who were able to "hack an exchange" doesn't already know this!
was it an inside job by a dumb employee who got access to the keys?!
Exactly, why would a supposed to be intelligent and smart hacker/s will simply move the tainted coins to a exchange, not just any exchange for that matter, but the top exchange we have right now. LOL. It doesn't really makes any sense. Even a casual crypto enthusiast knows how to used mixing services or tumbler to obscure the finger prints. So I guess another angle has surface, perhaps it was a inside job or something. Let's see how it pans out.
