Minimum bet in blackjack is traditionally set at 1 dollar, but some casinos may have minimums as low as 50 cents. The idea behind setting a minimum bet is to make sure that all players have an opportunity to win some money.
If the minimum bet is too low, then some players may not be able to afford to play and may lose money even if they are lucky. Conversely, if the minimum bet is too high, then some players may be able to afford to play more hands without risk of losing money.
