I understand the frustration here, but ultimately we all have to take responsibility for our own actions.  Rollbit provides platforms for high-risk gambling, yes, but no one forced your deposits or big bets.  After multiple losses continuing to risk life savings seems unwise and  rather than accuse and assign blame, it may be best to reflect on what lessons can be learned so similar mistakes arent repeated.  There are always healthier paths forward.

Let me ask you just one thing: If it had been any other casino besides Rollbit, would you have realistically expected a different outcome in your case? Did you ever expect to come to an online casino with money and guaranteed leave with a profit?
