Ethereum Name Service volatility and risk: how violent it has been
1,830 daily moves since 10 Nov 2021. On a typical day ENS moves 2.7% in one direction or the other; on 1 day in 20 it has lost more than 8.2%, and its deepest fall from a record close was −95%.
Volatility is the standard deviation of daily log returns multiplied by the square root of 365, the usual way to put it on a yearly scale. “1 in 20” and “1 in 100” are the 5th and 1st percentiles of all daily moves, read straight from the history with no model.
