a lot of smaller casinos are really hostile to players that win big. maybe because they dont have the bankroll to pay. i even read one casino here that agreed to pay but instalment basis. i forgot the name of casino. but at least, they made an agreement to the player to give his winnings.
so if you really want an assurance, just play in known casinos in the forum, without any outstanding complaints from their players.
cyber.bet is still up so maybe they are just banking from players outside the forum. i dont think they will come back again here and resolved their issues.
Well this one didn't have any problem, they just didn't want to let users withdraw their funds from the startbut I agree the lack of enough funds to cover for a user winnings can be one of the reasons for cases like this but if a casino website can not handle such transactions maybe they shouldn't be in this casino business in the first place, or if really only the lack of enough funds is the issue they could just have maximum deposit so that a user can not deposit and/or bet more than 5000$ for example.
At the end of the day they should be the one that predicts such problems that could happen and the user in no way should be responsible for their shortcomings.
