I mean when a gambler uses a small bankroll say $ 100 and uses a minimum bet of $ 0.1 it will definitely last longer on each bet to get a lucky chance.
but when a gambler uses a large bankroll, for example $ 5000 but with a bet amount of $ 100-$ 200 it will run out faster. because a big bankroll definitely has the mindset to win big with big bets too.
and as far as I know, the faster the bankroll runs out, the more difficult it is to manage our bankroll, the more difficult it will be to find opportunities for luck.
The explanation is because you are confident, thinking you still have more left even if you lose but you will only be shocked once there is only a small amount left in your balance. Another explanation is we are prone to rage betting once our early bets won't hit but we all can avoid it if we only have a minimal bankroll.
