: Experts recommend having a bankroll of at least 100 buy-ins for tournaments due to high variance. For cash games, some players suggest moving up stakes only once you have 30 buy-ins for the next level.
: Decide before you start if you are willing to rebuy. Only rebuy if you are playing well and were busted by factors outside your control.
: Buy-ins are often expressed as a range (e.g., $100–$200) or a set number of "big blinds" (typically 100).
: Beyond the buy-in itself, account for travel, food, and accommodation costs. Packing essentials like water and healthy snacks is also recommended for long sessions.
