1. Specified in Article 5.4(d)(i), (ii), (iii), (viii), (x), (xi), (xii), (xiv) or (xv), or Article 5.4(e);
2. A serious breach of Article 5.4(d)(iv).
The freeze on the Trading Account shall be lifted:
Pursuant to a written agreement between the Customer and CAEX;
Upon a decision to lift the freeze by a competent Governmental Entity in accordance with Laws;
Once the mistake or error in the funds/Crypto Asset transfer settlement referred to in Article 20.1(c) above has been resolved;
Once the case referred to in Article 20.1(d) above has been resolved. Where CAEX’s or the competent Governmental Entity’s conclusion on the handling of the case results in the closure of the Customer’s Trading Account, this shall be handled in accordance with Article 21 below.
Where the Customer and/or a competent Governmental Entity carries out or requests an unlawful freeze of the Trading Account causing damage to the Customer, the responsible party shall compensate for actual damage (if any) in accordance with Laws.
Notices relating to the freeze and unfreeze of the Trading Account shall be given in accordance with the Contract and by one of the applicable Notification Methods.

Where any abnormal sign is discovered, the Customer must immediately notify CAEX and take necessary measures to minimise the risks arising.

1. The Customer irrevocably agrees that CAEX may publish, amend, supplement, or adjust, at any time and through any Notification Method, its Policy and/or Online Trading Risk Disclosure Statement, without requiring the Customer’s opinion or consent, except where the Customer proves that the damage arose from CAEX’s direct wilful fault or fraud. In such cases, the Customer undertakes to comply with, and irrevocably accepts, CAEX’s published, amended, supplemented, or adjusted content. Where the Customer disagrees with such amendments, supplements, or adjustments after receiving CAEX’s notice, the Customer may request to stop using the service and carry out the procedures to close its Trading Account in accordance with CAEX’s regulations.
