It might be interesting to see a list of security measures you should take at physical casinos as the line between crypto and fiat currency betting is forever getting blurred. Things like avoiding the biggest drunks or people going through major mood swings. Keeping an eye on your chips at the table at all times, not being distracted by anyone - even if stuff is "accidentally" spilled on you for example. Watching your drink, because if people spike it you could potentially stand to lose large amounts of money. Keeping an eye out for collusion at the tables which may be working against you. It should be enforced by the dealer, but making sure people aren't touching the wrong places on the table that may interfere with the game.
Those are some great tips for someone who visits land-based casinos frequently. Another very important thing is to make sure that you are not being followed when you are going out from the casino, especially if you have managed to win some money and are headed back to your place. People often get sneaked up on and robbed when they get out of establishments where the attacker knows they have some money going back like banks, casinos, etc.
So, a person who gets out of a casino, alone, with some money or chips in the pocket, should first go to another public place, maybe use a washroom or something there, get into a crowd where they can get mixed in, and then sneak out from somewhere else so that if someone was following them they can lose them in the crowd and they don't get robbed and harmed.
If you were lucky enough to win big at the casino it would be a disgrace to be robbed just after it, however if you feel insecure you could ask some of the casino staff to escort you to your car and they will do it, as it is obvious casinos do not want that their lucky players lose it all because they were robbed as this will create negative publicity for them, still this is not a guarantee either as then you could be followed by the people trying to rob you and you could still lose your money anyway.
