Winnings from gambling comes unexpected and they are subject to proper management or excessive spending depending on the gambler's orientation.
Some gamblers have argued that the wins is not part of their financial plan, describing it as lucky and free money and they do not care how they spend it, but mainly use it for recreational purposes and to enjoy themselves by increasing their living conditions, partying and other forms of fun for a while, while there are others that apply more prudence in managing their winnings.
I like to think of my gambling wins as an income boost and depending on the amount, I always prefer using it to solve a particular issue or purchase a need that would always remind me of the winning.
Let's hear from you, how do you think gambling winnings should be spent?
Are you making a career out of it - like as a poker player, or are you simply winning one out of 20 sessions? If there is no skill involved in the casino game or sports bet you're playing, then you might as well just keep it in the account so you don't have to top up again later. If you're playing a game with skill, then you will be keeping a large balance in your account as a payroll and managing it to pay yourself out a salary on a regular basis or take it in big chunks. Probably want to keep the bare minimum required in a casino account, because if it's not in your bank then your account could be blocked or hacked which might take a long time to resolve. Take some out and treat yourself.
