Is there any harm in not using a bank card with CICC Wealth Management?

No.

General formal platforms have nothing to do with it, and you can unbind it if you don’t need it. Now, all official platforms have real-name authentication when registering, such as Wealth Management, to ensure the safety of users.

Opening an account with CICC Wealth Management is risky. The Guangdong Securities Regulatory Bureau issued a supervision and management warning letter, and CICC Wealth Securities received the warning letter for failing to perform its duties in accordance with the law. If you just bind a bank card, of course there is no risk. The risk only occurs after the account is successfully opened.
