If you think you have gambling problems, stop buying Bitcoin. Try avoid every possible site that contains gambling graphics. Gambling just like fapping once you start you can't stop. Go seek professional advice, I've seen someone try to recover he lost from casino but he ended up being a homeless. True Story mate.
Gambling problems do not stop by just stopping with buying bitcoins, I think you really need to convince yourself.
The reason is we still gamble even without bitcoin, in real life we can use our own currency and we are good to go. It's the problem that is coming from within, with the urge to gamble, no one can stop us but ourselves.
That true , but the struggle is real. If there a will there always a way. Make a new hobby or do something make yourself forget about gambling. Maybe spending more time with family and Friends. Gambling addiction not a joke, it can cause you mental illness.
Well I think that you can sign certain agreements to casinos that allows them to remove you if you enter their premises. Also bitcoin gambling i think is a lot more convenient than fiat gambling. You don't need to go to any place to gamble, you just do it on your laptop at home.
I think that using Coinbase vault or any other services that delays your withdrawal might help. Obviously you are putting yourself in a position of danger as Coinbase can disappear with your coins any time, but that's better than an almost certain loss in the long term gambling, right?

Now I never deposit any Bitcoin for gambling , I'm only withdrawing. So far I've make around 15 btc from tips and giveaway I get from casino isn't it cool? You don't have any worries to lose those money. Enjoy every bet you make. Win or lose that doesn't matter 😁
