You are right, many people are unaware of this particular term that some casinos have. And I am sure that some casinos don't have clear rules about this.
I never played in casinos from the list you provided, and to be honest, this is the first time I see that some casinos ask for more than x2 rollover for the deposited amount before withdrawing. X3 is crazy, and x10-x30 is unbelievable. It's some AML policy, and I guess some casinos need to compile some regulations, but this is ridiculous.
Nice share definitely. I will keep an eye on this thread... I don't wish to get trapped with my deposit and to be forced to wager some crazy amount just to be able to withdraw.
After knowing the hidden requirements for withdrawal then we never expected the casino to specify more than x3 to activate the withdrawal button, it's ridiculous that we only withdraw funds from our account balance but the casino arranges rules that are unfair to us, so hope every casino above should review again the rules above and better immediately revise for fair rules for gamblers.
