## Fat-Tailed Distribution

A fat-tailed distribution is a probability distribution that exhibits a higher frequency of extreme outcomes than a normal distribution. In financial markets, this means that large market crashes or massive price spikes happen more often than standard models would predict.

While normal distributions assume that extreme events are virtually impossible, fat-tailed distributions acknowledge the reality of market volatility. This concept is vital for crypto traders because digital assets are known for their high frequency of extreme price swings.

Using models that assume normal distribution often leads to a significant underestimation of risk. When risk managers fail to account for fat tails, they may be unprepared for sudden, catastrophic losses.

Understanding these distributions helps in building more robust risk management systems that incorporate the possibility of black swan events. It emphasizes the need for stress testing and conservative leverage limits.

By recognizing that extreme outcomes are part of the market, traders can better protect their capital. It is a cornerstone of modern quantitative finance applied to high-volatility environments.
