they are more concerned with the money which you invest in their site.
Statement that I like.
Conducting KYC for gambling sites is a topic that has often been discussed. And here there must be those who agree or not, that's not a serious problem. But most gambling sites don't do or apply it to every customer. Then just ignore it!
You have a point on that statement, just ignore when gambling site requires KYC. AFAIK, gambling casinos that require KYC are those accepting fiat. But now, they prefer to use cryptocurrencies because it is easy t use and far away from having KYC. Maybe those accounts that having suspicious deposits maybe will force to have KYC/AML to avoid money laundering.
