I highly doubt, op is likely not from Europe, if he was, he possibly wouldn't be asking for a casino that supports usdt withdrawal, knowing fully well that usdt is currently facing some charges from government in that region and may potentially be banned.

I personally believe ops choice of giving a special attention to usdt withdrawal is nothing short of usdt being the most popular stablecoin in the cryptocurrency market at the moment, and maybe conversion of usdt to fiat in his country is very simple and doesn't require going through any complicated process, this is possibly why he(op) made mention of usdt and nothing more.
