In accordance with the 'Investment Warning Designation and Trading Support Termination Policy,' we inform you of the termination of trading support for Quiztok (QTCON, Ethereum ERC20). Customers holding this virtual asset are required to check this notice and refer to it for their use. Quiztok (QTCON) will have its trading support terminated by the member companies of the Digital Asset eXchange Alliance (DAXA). Reference materials: Notice on Investment Warning Designation: QTCON DAXA member companies may take actions such as cautioning, designating assets as investment warnings, and terminating trading support to protect users. Therefore, customers holding this virtual asset must read this notice carefully and refer to it.

Reason for Trading Support Termination: Quiztok (QTCON) was designated as an investment warning due to a confirmed security incident involving a wallet managed by the issuer or operator. In addition, important matters, such as the security incident, were not disclosed, and after comprehensively considering the project's sustainability and actual progress, it was found to have several deficiencies with the potential to cause harm to users. After thorough review, including requesting explanatory materials from Quiztok, no evidence was found to resolve the reason for which it was designated as an investment warning. Therefore, to protect users, trading support for Quiztok (QTCON) will be terminated.

Cautions

• Deposit for the relevant virtual asset may be suspended upon investment warning designation or trading support termination. If so, additional guidance will be provided separately.

• For virtual assets whose trading support has ended, KRW value conversion is not possible, and all such cases will be subject to the travel rule. Therefore, you must enter recipient information or receive approval for withdrawal to an external wallet address (whitelisting) before withdrawal.

• All open orders will be collectively canceled after the trading support termination date.

• Existing trading history will be retained even after the withdrawal support termination date.

• To enable withdrawal support after trading support termination, you must be issued a deposit wallet address for the asset before the trading support end date.

• During the process of terminating trading support, unforeseen changes to laws, institutional requirements, or other circumstances may shorten the termination period. In such cases, additional notice will be provided separately.

• After the withdrawal support period has ended, you may still request withdrawals through the Coinone Customer Center. However, a certain withdrawal fee may be charged for assets for which trading support has ended. (Related link)

• For assets whose trading support has ended, technical support for mainnet changes, contract changes, airdrops, token swaps, and network updates may be discontinued, and the asset's value may decrease or be lost. Please ensure you withdraw all such assets within the withdrawal support period.

Coinone will continue to do its utmost to foster a sound and transparent virtual asset ecosystem. Thank you.
