Whether the platform is formal can be judged by the following methods:

First of all, we should look at the approval of the platform, and then see if the approval can be found in official website. If you can't find it, it's not a formal platform, but a small local platform. Such a platform is not reliable.

In addition, it depends on whether the funds are in the tripartite custody of the bank. Tripartite trust means signing deposit and withdrawal on CCB official website.
