Setting Limits
Once you've established a betting budget, it's important to set limits for individual bets. Many experts recommend betting no more than 1-2% of your total bankroll on any given wager. This helps to protect your funds and prevent large losses from a single bet.
It's also important to set limits for the total amount you're willing to lose in a given time period, such as a week or month. This can help prevent chasing losses and overextending your budget in a desperate attempt to recoup losses.
