That's why on good sites one of the responsible gambling features you can set is a maximum weekly deposit limit. The problem is that the problem gambler, when the compulsion sets in and he sees that he can no longer deposit on his site, ends up finding another site to deposit on and losing his money.
You provide a solution that you can refute yourself,
I don't mean to blame or laugh at you, but what you said is very true because even though the gambling platform applies a maximum limit on deposits, addicted gamblers will become other sites to play again. So it will still depend on ourselves, because we are the only ones who can control ourselves, not others, especially since it's just a site.
However, we can't expect anything from others, I mean even though they have such limitations but we are still in a situation that is controlled by emotions, then everything will end the same. Instead of looking at what the site can do or implement, we better look at ourselves so that we can control ourselves more and be responsible.
To be fair, this is a very nice feature but it cannot completely stop our gambling addiction if we cannot control ourselves. Not only in gambling but in any field, if we cannot control ourselves, no one can help us. But I support this idea because at least the casino is trying to come up with a solution to help players become aware of their out of control gambling behavior. If all casinos had this feature and required players to enable it, I believe it would help curb uncontrolled gambling.
But as you said, to be able to completely eliminate gambling addiction, the only way is to practice controlling our emotions, do not expect help from others when we do not try ourselves.
