Volatility

Volatility measures how much and how quickly an asset’s price moves over a given period. High volatility means large, rapid swings in either direction; low volatility means steadier prices. Cryptocurrencies are known for being more volatile than most traditional assets.

How it works

Volatility is usually estimated from the size of recent price changes — the larger and more frequent the moves, the higher the figure. It says nothing about direction; an asset can be highly volatile while trending up, down or sideways. Crypto’s volatility comes from factors such as evolving adoption, thinner liquidity than major currencies, and round-the-clock global trading.

Why it matters

Volatility is a core measure of risk. It affects position sizing, the width of stop-losses, and the appeal of stablecoins as a place to wait out turbulence. Higher volatility means larger potential gains and larger potential losses.

Example

A coin that routinely moves 10% in a day is far more volatile than one that rarely moves 1%, even if both end the month unchanged.
