There is a difference in etiquette between online and live blackjack. In live settings, players should be mindful of physical interactions, such as using hand signals to indicate their actions and maintaining a friendly atmosphere with fellow players and the dealer. Online, the etiquette is more focused on communication through chat features and respecting the virtual space without distracting others. While both formats prioritize respect and sportsmanship, the specifics of interaction and behavior differ due to the nature of the environment.
