Therefore, customers holding this digital asset are strongly advised to review this notice for reference. Reason for termination of trading support: It has been confirmed that there was a security incident involving the digital asset wallet managed by the issuer or operator of Quiztok (QTCON).

Therefore, for user protection, trading support for Quiztok (QTCON) will be terminated.
