It’s good if casinos are willing to cooperate, but even then, gamblers often find ways to get around restrictions. It’s actually easy to do especially with everything now tied to a single payment app. For example, if I have a friend, I could just rent his account to gamble. He earns a bit, I get to play, and that kind of setup can easily happen behind the scenes.
So instead of trying to limit access, which people can still bypass, a more feasible approach might be to increase the minimum deposit. That way, it adds a layer of friction without relying too much on strict controls, and it could naturally filter out impulsive or casual gambling.
Limiting the size of bankroll sounds reasonable on the face of it as it will lead to the responsible gambling process but as it has been stated, people will always maneuver around the loopholes provided they are severely addicted. The concept of minimum deposit hike is interesting as well as it amounts to a natural impediment, but may as well transfer the issue to an excessively aggressive loss to some. Fairly speaking, the main problem is self-control, and even a regulation could not be named fully-solved unless there is education and proper mental support. It is not enough to put people under constraints and limitations; they should be knowledgeable about the risks.
