It's been two months since the OP posted this topic, and he has yet to reply to questions and comments from the community. Therefore, I can only assume that your question will remain unanswered as well, along with other unanswered and much more important questions, such as listing shady casinos such as 1xbit / 1xbet, 22bet, melbet ... and other potentially suspicious sites.

As I said before, this is probably just a paid promotion for some casino sites, or maybe he's just promoting those sites with the best affiliate terms. Whatever the reason, this is not a review site that can be relied upon for accurate, unbiased information.
