## Theta Decay Management

Theta decay management involves optimizing a portfolio to benefit from or mitigate the effects of time passing, which erodes the extrinsic value of options. Since options are wasting assets, theta represents the daily reduction in value as expiration approaches.

Traders may structure portfolios to be net positive theta, meaning they collect premium over time, or they may manage theta to avoid excessive decay in long options positions. In cryptocurrency derivatives, where expiration cycles can be short, managing theta is vital for yield generation and cost control.

It requires a deep understanding of the relationship between time, volatility, and option pricing.
