Did Grant Thornton even make this information clear? They are so busy trying to maximise their own profits or for a better word income from the misery of others they might have overlooked it.
To be honest there will be many users refusing to send their KYC so those funds will remain unclaimed. They should divide any unclaimed funds between those that have claimed funds and try to increase their percentage of returns because the likelihood is nobody will get 100% of their losses covered.
If Grant Thornton end up pocketing more than it will become a bigger travesty than it already is.
The first and most important thing that GT has to do, is to find a way to verify users without such a complex system as they have now. Even if it's like all the other exchanges. It seems that they prefer users/ holders not to be able to claim their funds, thus they use this outrageous verification process and that makes it already a travesty.
