## Fat Tails in Crypto

Fat tails, or leptokurtosis, refers to the statistical phenomenon where extreme price events occur more frequently than they would in a normal distribution. In traditional finance, models often assume a bell curve, but crypto assets exhibit much higher probabilities of massive gains or losses.

This is due to the lack of circuit breakers, high leverage, and the reflexive nature of speculative bubbles in the digital asset space. When risk models fail to account for fat tails, they severely underestimate the probability of a catastrophic market crash.

Quantitative traders must use heavy-tailed distributions, such as the Student-t distribution, to better capture these extreme risks. Understanding fat tails is essential for setting stop-loss levels and calculating Value at Risk for crypto portfolios.

It represents the inherent instability and speculative nature of the asset class.
