I repeat, sportscasino.io works as agent system, that means no T&C, no KYC, immediate payments.
The site doesn't bother how it looks - its players are mostly persons known to the management in real life, site doesn't bother to gather reputation or fancy ads because it targets real connection with the high stakes player directly. It is rather a private club you are joining through real life reference than an online gambling site.
Anyone can give a try, you will like it.
It means that there are no place for common gamblers. I don`t see any reason to join some "private club" without any guarantee that doesn`t care about site and ToS. It would be more interesting to join some well-known casino without "known in real life".
As for me - the OP trying to invite as in some kind of scam. If they need gamblers - they can create thread here. If it is "private club" - they don`t need such threads like this. I don`t know what the OP wants, but i don`t ready to risk my money in such casino.
