The past few months has been bad for several exchanges as hackers continue making them the target, this is sad news for the exchange, hope they can coordinate with other exchanges so that if hackers try exchanging those coins for other coins they can be confisticated and returned to the true owners. But is it possible to move a large amount of coins without someone authorizing the transfer of coins.
What other Crypto wallet providers and Exchanges has been hacked in the last couple of months? You cannot identify coins that was hacked, because the hackers push those coins through Mixer services.
Also, who is going to "authorize" coin transfers? Have you ever seen anyone complaining that their coin transfer has been "waiting for approval" ....or are you just sucking things out of thin air to pump your post count? (Bitcoin has no centralized authority like a Bank that "authorize" coin transfers... it only happens when you use centralized (regulated) third parties.)
