Hello. This is Upbit, the most trusted global standard digital asset exchange.

Quiztok (QTCON) has been designated as a cautionary item, resulting in a temporary suspension of deposit services. (Enforcement Decree of the Virtual Asset User Protection Act, Article 17, Paragraph 1, Subparagraph (m))

*Quiztok (QTCON) was designated as a cautionary item by member companies of the Digital Asset eXchange Alliance (DAXA).

DAXA member companies may take measures such as issuing cautionary warnings, designating cautionary items, or terminating trading support to protect users.

Please see below for detailed reasons for the cautionary item designation. If you hold this digital asset, please review the following.

[Reasons for Cautionary Item Designation]

• Target markets: QTCON/BTC, QTCON/USDT

• Reasons for designation:

• Upbit has found, according to best practices for supporting virtual asset trading, that in the case of Quiztok (QTCON), the issuer or operator did not appropriately disclose key matters through appropriate electronic delivery media in a timely manner, had incidents of security breaches such as hacking, and other aspects relating to the authenticity and sustainability of the business were found to be lacking, making it likely to cause potential user harm. Therefore, Upbit designates 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 typically conduct a thorough review to determine whether to extend, lift, or ultimately terminate trading support for the relevant digital asset.

• After the cautionary item designation, Upbit will review the reasons for the designation according to 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 designation may be extended. If the reasons for the designation are not fully resolved, trading support may be terminated.

• If the review period is extended or if trading support is determined to be terminated, a separate notice will be issued, and the exact schedule will be provided in that notice.

• For digital assets designated as cautionary items, deposits will not be reflected after the time this notice is posted, and all deposit attempts will be subject to return.

• Designation of cautionary items and trading support termination by Upbit are in accordance with the [Digital Asset Trading Support Termination Policy](https://static.upbit.com/guide/market_policy_close.pdf).

[Notice of Temporary Suspension of Deposits]

• Affected digital asset: Quiztok (QTCON)

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

• Notice for deposit resumption: Guidance will be provided according to procedures after the cautionary item designation.

[Important Notes Regarding Deposits]

• After the deposit support suspension time, deposits of QTCON may not be credited to your Upbit account, and in such cases, recovery may not be possible. Please do not make deposits after the suspension time. During the deposit support suspension period, the deposit return process for the relevant digital asset will also be temporarily suspended, and deposits will be returned sequentially after the deposit support is resumed.

• In the event of a deposit suspension, deposit processing may be delayed due to network congestion, and there may be differences between the blockchain network’s transaction confirmation time and the actual reflection time on your account.

• Deposits may occur on certain blockchain networks before or after the deposit suspension time, but depending on the status of our wallet system processing during maintenance, proper processing may be impossible during the maintenance period. After maintenance ends, deposits will be processed sequentially following verification, which may cause delays in reflecting them to member accounts.

• In cases of unexpected maintenance such as wallet or network system checks, deposits may occur on certain blockchain networks before or after the notice. However, if processing cannot occur during maintenance due to the status of our wallet system, deposits will be processed sequentially after verification, possibly resulting in delays in reflecting them to your account.

• Any special information regarding the resumption of deposit support will be announced through this notice.

Upbit will always strive to ensure your safe trading experience.

Thank you.
