What Altcoin Volatility Tracker does
This tool measures how much a coin's price has actually been swinging, using live market data to calculate its real 30-day volatility — the standard deviation of daily price changes, plus the single biggest one-day move in that window. "Volatile" gets thrown around loosely in crypto commentary; this turns it into an actual number.
How to check a coin's volatility
- Enter a coin's name or ticker symbol, such as "dogecoin" or "SOL".
- Select Check volatility.
- Review the volatility level, the daily swing (standard deviation), and the biggest single-day move over the past 30 days.
Reading standard deviation as a volatility measure
Standard deviation of daily returns is the industry-standard way to quantify volatility: a higher number means daily prices have been swinging further from their average, a lower number means they've been comparatively stable. The biggest single-day swing figure catches sharp one-off moves — a single news-driven spike or crash — that an average alone can understate.
What this isn't
This measures what has already happened over the past 30 days — it is not a prediction of future volatility or price direction, and past volatility is only a loose guide to what's ahead. Use it to compare coins against each other or to understand the risk profile of a position you're holding, not as a signal to trade on.
