Having an excessive bankroll in gambling wouldn't stop you from having a limit to the resources that you gamble with. If you don't have an amount set aside for gambling you will stake above your means without realizing yourself. Most people don't know how easy it is to gamble with a thousand dollars, that money can be everything you have and it can be exhausted in a Twinkle of an eye. The More you keep funding in the process of chasing your losses the more you keep throwing all your money away. Having an excessive bankroll doesn't mean that it's inexhaustible.
Having excessive bankroll as a gambler can be quite interesting but sometimes this will not help us to be a conscious and discipline gamble because we might want to try to gamble on every gamble on every game that we see trying to make consistent profits. It is better we regulate our everyday gambling so that we don't have to do it too much. Gambling is majorly to make profits not to deposit heavy funds in the bankroll for the sake of gambling for bigger profits. We can also make consistent profits as a gambler having smaller bankroll without doing it too much. I don't support having huge bankroll in our gambling portfolio when we can always withdraw part of the fund.
