In my opinion, movies, anime, TV series romanticize the casino theme too much. It may not be as simple and easy as it seems from the outside. I know many people who lost their last money there.. You need to be very careful with such a hobby.

If we talk about security, then it is worth considering sports betting. Modern bookmakers work on the principle of online service. Here is a good example from India - https://1xbetinapk.com/ All you need is to have an account and double authentication. I think that bookmakers work more honestly than casinos.
