I'll stay here till my balance runs out.
Hmm, why dont you hope to get your balance doubled/trippled or even more? Saying "till my balance runs out", it sounds like that you have no plan to cash out when you are on profit or win big. Although it is your own money and you can do whatever you want with your money but I think it is better to have a target. Sorry if I misinterprete your words.
Not everyone really gambles to make money or profit, including me. I just like to gamble to have fun, it is a way to spend some time for me and not something I am planning on making money neither. You do not go to movies and try to earn money right? You spend money there. You do not go out to eat somewhere and try to make money right? You only spend there. There are a million things that people do to spend some time and almost all of them equals to them spending money and no way of earning.
Yes, there is a way to make some money with gambling so people do not see it as spending money, however I do, I see this as something I can just have fun with while spending some money. I do not spend too much money neither, it is like less than 5 nights out for me and I spend like a week with that money anyway so basically I spend less money.
