I have some token on xhash from after the fork too. But never transfered it to my wallet. They`re still sitting at xhash.
But i own more than 2500 pre-fork etoken too. Would be very hard if they`re worthless.

I think it`s not possible to fork out the bank. That`s the problem with a 15% premine, even if it`s called bank. You have to trust the dev.
