Leptokurtic Fee Spikes

Kurtosis

Leptokurtic Fee Spikes describe periods where the distribution of transaction fees exhibits a high positive kurtosis, indicating a greater likelihood of extreme, sharp upward deviations from the mean fee level than predicted by a normal distribution. This statistical signature signals significant, sudden market stress or intense competition for immediate block inclusion. Traders must account for this fat-tailed risk in their derivative pricing.
