[Reason for Designation as a Cautionary Item]

• Target markets: QTCON/BTC, QTCON/USDT

• Reasons for designation

• Upbit, in accordance with exemplary practices for supporting virtual asset trading, has confirmed that Quiztok (QTCON) either fails to disclose important matters in a timely and appropriate manner through electronic transmission media by the issuer or operator, or there have been security incidents such as hacking, and found that multiple deficiencies may exist when comprehensively considering the business's viability and sustainability, which may result in user loss. Therefore, Upbit is designating Quiztok (QTCON) as a cautionary item to protect investors.

• Cautionary item designation period: July 10, 2025 (Thu) 17:00 KST \~ July 23, 2025 (Wed) 23:59 KST

[Next Steps After Cautionary Item Designation]

• Once designated as a cautionary item, Upbit will generally conduct a detailed review of the digital asset to decide on the extension, removal, or termination of trading support for the cautionary item.

• After the cautionary designation, Upbit will conduct assessments on the reasons for the cautionary item in accordance with the [Digital Asset Trading Support Termination Policy](https://static.upbit.com/guide/market_policy_close.pdf).

• During the review process, the review period for the cautionary item may be extended, and if issues are not completely resolved, a decision may be made to terminate trading support.

• If the review period is extended or support termination is decided, announcements will be provided through separate notices, and the exact schedule will also be announced accordingly.

• From the time this notice is posted, deposits for digital assets designated as cautionary items will not be reflected, and all such deposits will be subject to refund.

• Upbit's designation of cautionary items and trading support termination for digital assets is in accordance with the [Digital Asset Trading Support Termination Policy](https://static.upbit.com/guide/market_policy_close.pdf).

[Notice of Temporary Deposit Suspension]

• Target digital asset: Quiztok (QTCON)

• Deposit suspension time: 2025-07-10 (Thu) 17:00 KST

• Notice for deposit resumption: To be announced according to the procedures after cautionary item designation

[Important Notes Regarding Deposits]

• After the deposit support suspension, if QTCON is deposited, it may not be reflected in your Upbit account and, in such cases, recovery may not be possible. Please ensure that you do NOT deposit after the deposit support suspension time. During this suspension period, the refund process for deposits of the affected digital asset will also be paused, and they will be refunded sequentially after deposit support resumes.

• If a deposit suspension occurs, deposit processing may be delayed due to network congestion or other reasons, and there may be a difference between the confirmation time of the blockchain transaction and the time the deposit is reflected.

• Deposits may occur on some blockchain networks before or after the suspension, but depending on the wallet system's operational status, processing cannot be completed during maintenance, and will be processed sequentially after maintenance ends, which may result in delays in the user's account.

• For unscheduled maintenance such as wallet checks or network updates, some blockchain deposits may occur before or after the announcement, but due to the operational status of the wallet system, they cannot be processed during maintenance, and will be reflected sequentially after checks are completed, causing possible delays in user accounts.

• If any special issues arise regarding the resumption of deposit support, we will provide updates through this notice.

Upbit will always do its best to ensure the safety of your transactions.

Thank you.
