Betting progression in blackjack, which involves adjusting bet sizes based on previous outcomes, can be seen as a strategy to manage bankroll and potentially increase winnings or minimize losses. While some players find success in using progressive systems, such as increasing bets after losses to recover losses or decreasing after wins, the effectiveness is largely limited by the house edge and the inherent randomness of the game. These strategies do not alter the fundamental odds and can lead to significant losses if players experience long losing streaks.
