High volatility means larger wins but also greater losses, while low volatility offers more consistent but smaller wins. Understanding volatility is crucial for managing your bankroll effectively when gambling. Players should consider their risk tolerance and desired level of excitement when choosing games with different volatility levels. Overall, volatility plays a significant role in the gambling experience and can influence the outcome of your gameplay.
