I guess you will become rich with your bitcoin hoardings and you will come back to gambling after you become rich.
I don't think he will still come back to gambling after proving to himself that getting rich from gambling is just an illusion. And the only way to get out of bankruptcy is through hard work. He already knows the value of hard earned bitcoin and will not risk to lose it on a game of gamble. I also believe that staying away from gambling even when you are rich is a smart choice.
I just hope it is true to all rich person in the world, but it is not. Maybe at first, they can manage properly their gambling habit. But it will be a different story if they become addicted to it or they become compulsive gambler. They can be ruining their financial status or even their life and they would not even mind it.
