I see at BTC365.com that they are licensed from Montenegro. That immediately reminds me of the Cloudbet platform, but I don't think this is a Cloudbet project. I also don't know if this site is reliable. They don't have an ANN on Bitcointalk and I can't find a lot of info about them either. Founded in 2020 so it seems, so still fairly new on the market. That doesn't always mean much. You will have to look and judge based on reviews from other players whether or not you are going to play here. I wouldn't put any money into it right now.
I definitely agree with your statement.
Not to be biased against Chinese gambling websites but in order to secure your money, better bet and use your funds in a more reliable online gambling platform with a designated ANN thread in this forum. With that in mind, communication between you and their service is relatively easier and closer. While their website may not offer any KYC documents, you are still putting yourself at risk in the event that a conflict arises.
Like what I always say, prevention is always better than cure; put your money in a more secured and reliable website instead!
