Thats probably the most fundamental thing in gambling, you need some funds to gamble and people cant do that when they have nothing on their possesion however even if it is 1 cent it is still considered as gambling and of course waiting till you lose everything from gambling is not something that might help people to quit for good
(Well I realized this probably right now)
At least for the people who have a lot of money that would be the best way. The thing is some people are poor and they are still gambling borrowing money for that. That's a real hell IMO, hell for them and hell for those who live with them. I think the first rule in gambling should be "Never borrow money to gamble".
We should not push ourselves up to the level that we will not enjoy gambling anymore, it is still advisable to just play it for fun that seeking money from it.
