I think adjusting your bet size based on the game's volatility and your bankroll size involves finding a balance between maximizing potential wins and minimizing risk. As volatility increases, consider reducing bet size to avoid significant losses. Conversely, during periods of low volatility, you may increase bets to capitalize on more predictable outcomes. Bankroll size also plays a crucial role: with a larger bankroll, you can afford to take on more risk and increase bet size, while a smaller bankroll demands more conservative betting.
