You can ask to casino or exchanges to know more details about the fund. But I guess they will not tell you about that because that is their privacy. They can take it to the government or keep it for them so we will not know about that. But I don't know if casino will flagged our wallet address if we send that fund because they will not tell to us and if somehow they are suspicious, they can do that easily without telling us. But if that wallet address is not contain with suspicious activity, they will not do that. That is what I am thinking so I could be wrong as I don't know the truth.
