It's difficult before you can see a casino platforms that have license that make away with the players money, it's very difficult, and secondly if such should happen it will be an old casino who wants to close and they can run a scammer because they are living or by the end of shouting the platform down, so a reputable casino is the one who have a licence and also mandates all their players for KYC verification, and which network of both withdrawal and deposit is very fast in payment and withdraw.
I think we already had multiple casinos on this forum that were licensed (under Curacoa) that ran away with peoples money. Also asking all players KYC verification, doesn't make a casino reputable, why would that be the case? It is a fact that more and more casinos ask KYC but that is another discussion.
