What is bankroll?
The notion that bankroll relates to a butt-load of money is wrong. Bankroll does not necessarily mean big. Bankroll simply is the amount of money you are willing to wager for, let's say a day, or a week.
Simple.
Whatever amount of money you take with you on your way to Las Vegas, that, my friend, is your bankroll. Whatever amount of money you have for wagering on basketball or football, that, my friend, is your bankroll.
The moment your bets exceed the amount of your bankroll, you place one of your size elevens squarely on the proverbial banana peel and start your descent.
To sum up, bankroll is your money you just made available for your favorite sport called sports betting.
