Online tournaments generally require a larger bankroll due to higher variance, faster structures, and more frequent play, leading to greater swings. Live tournaments, while having softer fields, involve higher costs such as travel and accommodations, making proper bankroll management crucial. The slower pace of live play can reduce variance but also limits volume, impacting long-term profitability. Balancing both formats requires adjusting bankroll strategies to account for these differences in risk, expenses, and potential returns.
