Are these real ? If so then everyone else with a cryptopia altcoin trading account should get one too, and somebody will post here a report of getting back some of their old altcoins. If not then I have no reason to disclose anything to the entity who now have the list of user emails.
If you are willing to give your private documents, you maybe get refunded with the coins you had in cryptopia during the hack.
KYC is mandatory.
