Handling a losing streak in blackjack requires staying calm and avoiding emotional decisions. It’s important to stick to your established strategy and not make impulsive changes in an attempt to recover losses, as this can lead to bigger setbacks. Managing your bankroll effectively by reducing bet sizes during a losing streak helps preserve your funds and extends your playing time. Setting a loss limit before playing ensures you don’t risk more than you're comfortable with. Taking breaks when needed can help clear your mind and refocus, while accepting the natural variance of the game helps maintain perspective. Staying disciplined is key to weathering the ups and downs of blackjack.
