I think they already run away with their players money, these days it's really hard to play on a new casino platforms since you don't know if they would be legitimate or not or soon they will be like this running away with their players fund but we can't blame users since some of them offers really tempting promos.
If you don't see a license in a casino don't dare to Stop there for a single moment.
Moreover ask them about their bankroll and if possible a signed message from the cold storage wallet that is holding the funds.
IMO it's better to avoid new sites at first untill and Unless they do some serious sort of advertising and promotions.
There are already a lot of sites present also with a ton of variety of games.
Play and invest there , and if your luck favours then you will surely win.
Always try to be cautious and avoid from being getting scammed.
