I used first deposit bonus on woopwin casino. I wagered my bonus and won up to 500€. I tried to withdraw my money and day later all my money was gone and my original deposit (25€) was my only balance. I contacted live support and they said all of my money got removed because when I was wagering I betted higher than 4€ (I played 6€ blackjack).
I think this is such a scam, there was no notifications or warnings that you cant bet higher. I also think its wrong to support sites like these in casinogrounds 😕
