You're right. Platform security is the cornerstone for any project. And for a project that is a platform for gambling, this is the main concept.
I would honestly check such projects very carefully, I have nothing against this platform, but still people here play and spend their time
It is possible that in the future they will make such an organization that will control this whole matter, or rather, just check the documents for the developers' reality.
If there are such guys, then most of the projects will simply not be able to deceive people anymore, but they may find a new way
