Bankroll management in blackjack is the practice of allocating and controlling the money set aside for betting to ensure sustained play and minimize the risk of significant losses. This involves setting betting limits, adjusting wager sizes based on wins and losses, and establishing stop-loss and win goals. Effective bankroll management helps players avoid emotional or impulsive betting, which can lead to rapid depletion of funds. By maintaining discipline with their bankroll, players can better navigate the natural fluctuations of blackjack, maximizing enjoyment and increasing their chances of long-term success.
