He is probably looking at their longevity as he has been with them since 2021 with no issues. However, the recently developments that he noticed are serious red flags that things are about to go south with that casinos. Introducing weekly withdrawal limits where there were none before and introducing other conditions like the OP said, will make me worried if I have my funds in that casino.
Longevity with fair to bad reputations. What a gambler should look for in a casino is reputation. What people should be expecting from the casino now is accounts restricted from withdrawing. It is possible that the casino misappropriated their customers money and not having enough money as before. But if the casino do not fall now and still has customers, theybeilk gamble and lose and the casino will rise again. But I will prefer to just leave the casino. There are many better caisnos.
