For and addicted gambler, no amount of profit will stop them from gambling because they are addicts.
For reasonable people though this is not true and one might stop after winning a set amount of money. But there's no end of greediness.
In my case, I will stop after winning 10 BTC because I'll be too busy Driving my Porsche instead of Gambling^^
How many BTC it would take for you to quit gambling and why? Or, if any amount of BTC would make you quit gambling at all.
With your Porsche, other rich people will be socializing with you and you would need money to be able to keep up with them. At first it's all good because you still have some money left. On the other hand, this life will go on because you are going to enjoy it and you wouldn't want it any other way. Of course if this actually happened to you, you will have some resistance to gamble because you would want to stand for your words.
You are just human and being human means having insatiable desires. You might say that you're going to be content with 10
BTC and the things that you can buy with that amount of money but let me tell you something, once you're in that situation, your human instincts will kick in and you will continue to gamble. You're not greater than your human instincts unless you have trained long enough to be in control of them.
I'm not an addicted gambler and I don't gamble at all. Maybe just at times when I want to but I honestly think that it's a waste of time so I stopped gambling. But, that doesn't remove my knowledge about some basics of psychology and knowing that I'm just a human being with human instincts is one of them. I think some people might gamble even more once they have made tons of money from gambling.
