if someone really want to stay away from gambling, i think this is the best suggestion. you will not ever in future will try to gamble.
1. make a bet on gambling site and with all the btc you have and play until you make sure you lost all. you will fell very bad, you will not be able to sleep few days and than you will make your mind never to gamble again
2. your gov bann the online gambling in your country.
Not really the best suggestion imo,
1. Why you need to lose all your money to stop gambling while you need your money for living. Once you lost all your money, what will you do without any single cents?
2. It is discussed many times before. Even though gambling sites are banned, you are still able to access those sites with VPN or other services to unblock those sites.
