Which options have the highest Vega?

As a keen observer of the cryptocurrency and financial markets, I'm often curious about which options exhibit the highest Vega. Vega, as we know, measures the sensitivity of an option's price to changes in volatility. In the rapidly evolving landscape of crypto derivatives, where volatility can skyrocket in an instant, understanding Vega becomes paramount. Could you elaborate on which options, in your opinion, tend to have the highest Vega? Are there specific types of crypto options, such as perpetual swaps or futures contracts, that are more volatile and thus exhibit higher Vega values? I'm particularly interested in strategies that leverage Vega to enhance returns or hedge portfolios.
