I agree with that. We can set up a budget on any game that we choose and it's up to us if we will keep the discipline or not.
I know it can be frustrating sometimes when we already hit the budget amount for the day and we still haven't received any good multiplier after all the bets we made.
Having a budget for gambling is a very good idea. By setting a budget for gambling and abiding by it, one will be disciplined and may hardly get addicted to gambling. Once the money you allocate for gambling is finished, you will end gambling for that day, week, or month. In fact, it is not only for gambling but for other things too, so that you will not spend more than the money you allocate unless it is an emergency. As for me, I always have the amount I allocate for gambling per month. If I mistakenly use it during the week, I quit gambling for that month until the next month. So, if gamblers budget for gambling, I think it will help avoid spending too much on gambling.
I have been through that situation and I learned my lessons in a difficult way. My thoughts were just to use $5 per week and I am surprised to myself that I can go further if I want to.
If someone is not addicted to gambling, I believe they should be able to discipline themselves so that they do not spend more than what they have budgeted for gambling. But still, I don't know why I am always able to control myself after I have spent my budgeted amount. I always find it hard to continue gambling more. Or maybe it's because I am gambling for fun.
