Its really bad for kids because we know that kids on their ages they don't have money to gamble the tendency there is them to steal money to gamble because its so addicting and what is so much strange is to let them to do bad things just to make money to gamble.
Gambling is like drugs that prohibited on children . Only the parents can guide their kids in the right path and for them to not be so strict  so the kids will dont do any move to revenge .
