Some adults will not know when they stopped enjoying gambling to become addicted. They are adults they should know better, they should not become addicts but gambling company owners have a responsibility to protect children and gambling addict adults from harm. There is no best way to gamble.
Minors must stay away from gambling, I will not allow them to gamble in any way, the only job of minors is to educate themselves through proper education, they do not need any money now, so they should stay away from gambling completely. At this time, if they need entertainment, they will play physical games, they have no rational reason to gamble, so especially minors must stay away from it, and for this, their guardians should keep a close eye on their children.
