Expiration refers to the end of a defined period during which a cryptocurrency option or contract is valid. Once this time frame is reached, the contract becomes void and cannot be exercised. In trading, expiration dates are crucial, especially for options and futures. For options, this date determines whether the holder will exercise their right to buy or sell the underlying asset at a predetermined price. If the option is not exercised before expiration, it loses its value.In addition, some tokens or coins may have expiration policies related to staking rewards or locked incentives. After a set duration, users may lose access to certain benefits if they do not meet specific criteria.Understanding expiration is essential for traders and investors, as it impacts decision-making and the potential for profit or loss. Being aware of these timelines helps in strategizing trades and effectively managing investments.
