I was testing the waters with some new casinos and came across Ice Casino with close to perfect review by Casino Guru, sadly as they are allegedly sponsored by them, the truth is Ice Casino has a very bad reputation when it comes to withdrawals. My experience with them so far, I got lucky enough to win 2.500 euros at their casino, got my account approved relitively quickly and asked for a withdrawal to Mifinity (which is instant, depending on the casino finance department actions). The first red flag, they split my withdrawal into 3 increments of 1k, 1k, 500. The sole reason they do this is for stalling the withdrawals allowing you to cancel them at any time, which might be a serious issue for people with gambling problems. So they managed to withdraw 1k in couple of days and the rest is just "pending". In reality they are just waiting for me to cancel and lose it, which is another red flag from a casino. After chatting with a customer support on the status of the withdrawal they are just sending the same template answer of "30 day withdrawals, 5k limit etc etc" which is useless in general.
So if you are reading this before choosing where to play, do not register here if you don't want to have any problems with withdrawals. There are plenty of great casinos that does fast payouts with a smile on their face knowing you'll be playing there without any issues.
