Many people are confused about what a European option actually is and how it differs from its American counterpart. Let's clarify. A European option is a contract that grants the right to execute the transaction only on the expiration date. Not earlier, not later. At that moment, you can either buy or sell the underlying asset at a predetermined strike price. If the term has passed and you haven't exercised your right, the contract simply expires. The difference from American options is significant. American options can be exercised at any time before expiration, providing much more flexibility. But this flexibility comes at a cost — American options are usually more expensive. A European option is a more predictable instrument because you know exactly when the exercise will occur. When it comes to a call option, you have the right to buy the asset at the strike price. If the price has increased, your contract is in profit. With a put option, it's the opposite — you can sell at the set price, benefiting if the market has fallen. An important point: this is a right, not an obligation. You can simply choose not to exercise the contract if it's not advantageous. Although traders usually don't let contracts expire worthless if they are in the money. In crypto trading, European options are becoming an increasingly popular tool for hedging and speculation on assets like XRP, SOL, BNB. Thanks to the predictability of exercise, these contracts are convenient for portfolio planning. If you work seriously with derivatives, it's important to understand the differences between option types to choose the optimal instrument for your strategy.
