Taking insurance in Blackjack is generally not recommended for most players. While it may seem like a way to protect your original bet if the dealer has a blackjack, the insurance bet has a high house edge and is statistically a losing proposition over time. The probability of the dealer having a blackjack doesn’t justify the 2:1 payout, and the bet is designed to favor the house. In most cases, it's better to avoid insurance and focus on playing the main hand. Only advanced players who count cards might consider it under specific circumstances, but for most players, it's best to skip it.
