As long as they can learn from their mistakes and are willing to seek more information, I'm sure they will eventually be able to tell or feel if the casino is a scam.
Perhaps it should be added that finding information about new casinos can be a little difficult, simply because there is still too little information on the network as a whole.
But by the way, experienced players have some kind of "fifth sense" on how to figure out fraudulent casinos. After all, this itself comes to mind "from somewhere above" based on the smallest nuances in the descriptions, rules, or even after entering directly to the site of this casino. Even despite the beautiful design, such a player begins to feel that something is wrong. Either the conditions are too good for the player, or the onuses are too good. After all, the scammers have only one goal - for you to send them money for a deposit. And then they themselves will decide where to put them.
So in the end, I think that scammers can now only cheat very naive and inexperienced, novice players.
Experienced ones are unlikely to fall for their hook.
