Does your “friend” bet on same matches as yours but on opposite side? Because there’s no problem if you both on same matches on same exact pick. But if you’re always have a contradicting bet then this will surely raise a suspicion for arbitrage betting which is not allowed in the casino because you can freely get rakeback and other passive reward such as airdrop and lvl up reward without losing anything.
But at least you should recover your initial deposit unless the other account successfully manage to withdraw the balance which cover your initial deposit. This story of yours about multiple account that involves family, friends and other relatives is the common reason of those players caught doin arbitrage bet and different kind of abuse.
FelixH is a liar. He lied to me in telegram. Before reaching me in telegram from his Felix account, he reached me from his original account. I got his message notification in telegram. As I was busy, I didn't check at that time. When Felix reached me, surprisingly the previous message from his original account was deleted.
This guy has alt account bitcointalk (his main account who has problem with almost all the casinos). I don't want to mention who I'm talking about. I had tried my best to help him in another case but I'm now getting convinced that he is an abuser as he didn't bother to lie when he reached me in telegram.
