Just like you said when you Fear of losing money to gambling then the best idea is to not gamble at all i mean seriously if you try gamble at first time and then you win lot of money it can lead into addiction if you can control it. and could be worsened if you addiction is fuel your mind.

I have a cousin that really addicted to gamble and he just divorced because of it, he taking loan to his father in law and other person till hit couple of million IDR and cant make it back.

If you do gamble for fun and don't care if you losing the money then go ahead
