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.
Limiting our reach to money is a better strategy for gambling and that is what I used when gambling. As we start gambling, we can get lost in the excitement that we are getting from enjoying the games that we are playing or we get frustration from the losses that we are getting from the games therefore when we have excessive bankroll, we are not doing any good to our money because we are going to lose them gambling unnecessary or trying to revenge our losses and that is the reason most gamblers lose money because they do not know when they should quit because of the mindset of revenge. Having more money would not make you to win more when gambling instead it will increase the possibility you have of losing more money.
