Yes, because gambling cannot be used as a stable source of income, management becomes difficult.
Cannot? That tells it's impossible, I beg to disagree with that as I believe it's possible but chance of making ourselves successful is very slim. So let us not use the word cannot or impossible.
One good way to manage gambling is to set a budget limit for gambling, such as 10% of your monthly salary or other percentage. We cannot determine how much profit we will get because there is no guarantee that we can win, therefore we need to determine spending limits because that can be determined
But it's best not to expect too much from gambling, because often we don't get wins but continuous losses which will worsen our financial condition
10% is not so high with low income people. honestly, I'd rather gamble using a decent bankroll on an occasional basis rather than doing it monthly with a bankroll that doesn't bring a lot of thrill in my gambling session. I find it a waste of time and I might only be wasting money even it's little by little.
