Cryptocurrency exchanges have set up professional risk management departments to control and manage potential risks through a series of measures such as account freezing and C3 methods. The following are several situations that may lead to the account being taken action by the risk control department:

1. Accounts that only purchase but do not sell virtual currency on a daily basis and withdraw cash immediately after purchase.

2. The account lacks virtual asset transaction records, but frequently recharges to sell virtual currency.

3. Accounts whose relevant ICBC accounts have been frozen due to issues with the source of funds and have been reported multiple times.

4. The currency dealers did not implement real-name payment and thus received multiple customer complaints.

5. Involving legal cases, resulting in the account assets being frozen by judicial authorities.

6. Accounts holding large amounts of assets, especially when these actions are linked to misconduct in the small-dollar trading market.

7. Accounts that received illegally obtained virtual currency, which is usually related to actions taken by industry insiders to prevent losses rather than illegal activity directly tracked by law enforcement.

8. Any act that infringes upon the interests of the Exchange by using advanced technology, such as making improper profits through automated trading or by taking advantage of exchange promotions.
