I must say agreeing on this because the very moment that they deny players from withdrawing their legit wins meaning that scamming already take part.
That's likely the case, why would they deny the withdrawal if it was won by the player in a legit way?
Only shady casino will only do that and tha'ts the problem of the players who had the chance to win big but unfortunately unable to withdraw.
The reason why we need to choose which gambling site we're going to play, and obviously this one is not included.
