You know what's best for your kids. As a gambler, you know the possible side effects of it and do you think that's good for your children to experience it? No.

And not just that, where they're going to get the money that they'll gamble? If they are grown up already and can work for their own finance then it's for them to decide to gamble or not since they earn their own money.

Don't show them that you gamble, block off sites that will introduce them to it with the devices that they use.
