Trading support for Quiztok (QTCON) will be terminated by the member companies of the Digital Asset eXchange Alliance (DAXA). Reference material: Notice on Designation of Cautionary Item: QTCON DAXA member companies may take actions such as issuing warnings, designating cautionary items, or terminating trading support to protect users. Therefore, customers holding the relevant virtual asset are strongly advised to check this notice and refer to it for their use. Reason for termination of trading support: It has been confirmed that there was a security incident in the virtual asset wallet managed by the issuer or operator of Quiztok (QTCON), and that there was no disclosure of important matters such as the occurrence of the security incident, and that there are still many insufficient aspects regarding business sustainability and ongoing progress, raising the possibility of user damage. As a result, it was designated as a cautionary item. Afterwards, we carefully reviewed and requested explanatory materials from the Quiztok team, but no evidence was found to justify lifting the cautionary designation. Therefore, to protect users, trading support for Quiztok (QTCON) will be terminated.
