In Options Trading, What Greek Letter Measures the Sensitivity to Volatility, and How Does This Relate to Mining Variance?

The Greek letter that measures the sensitivity of an option's price to a change in the underlying asset's volatility is Vega. A high Vega option is highly sensitive to volatility changes.

This relates to mining variance because a miner's profitability is highly sensitive to the unpredictability (variance) of block discovery. Just as Vega is key to options pricing, variance is key to a miner's cash flow stability.
