## Kurtosis and Fat Tails

Kurtosis is a statistical measure that describes the peakedness and the tails of a probability distribution. In finance, high kurtosis indicates that the distribution has fat tails, meaning that extreme events occur more frequently than they would in a normal distribution.

Cryptocurrency markets are notorious for fat tails, as they experience frequent and severe price shocks. Standard financial models that assume a normal distribution often underestimate the risk of ruin in crypto.

Traders must incorporate fat-tail analysis to properly value deep out-of-the-money options and manage leverage. Recognizing these tails is essential for building robust risk management systems that can survive black swan events.
