Ether Realized Volatility (30-day)

## What this measures

The standard deviation of Ether's daily log returns over the last 30 days, annualized by √365 and shown in percent, computed by Palanor from licensed daily closing prices.

## Why it matters

Ether usually moves more than Bitcoin. The gap between the two is a read of how far risk appetite reaches beyond the largest coin.

## How to read it

Percent a year. Since 2021 it has run from 15 (August 2023) to 206 (June 2021). Yearly averages were 101 in 2021, 85 in 2022, 45 in 2023, 62 in 2024 and 73 in 2025.

## What it does not say

It looks backward over one month and says nothing about what options markets expect. A day missing from the price record breaks the window, so no reading is published until 30 unbroken days return.
