What is a crypto fear & greed index?

The Crypto Fear & Greed Index distils the market's mood into a single 0–100 number, from Extreme Fear to Extreme Greed. It's one of the most-watched sentiment gauges in crypto because it's contrarian by nature: peak fear often marks local bottoms, peak greed often precedes corrections. This dashboard shows the live score on a colour-coded gauge, the current label, the last 30 days of history, and quick context (yesterday, last week, last month) — all from a free, keyless data source. Cryptohopper.AI builds it from a sentence, with a distinctive gauge UI you can restyle or extend.

Veelgestelde vragen

What is the Crypto Fear & Greed Index?

A 0–100 score that summarises crypto market sentiment — 0 is Extreme Fear, 100 is Extreme Greed. It blends volatility, momentum, volume, social sentiment and Bitcoin dominance into one number, updated daily.

Does it need an API key?

No. It uses the free, keyless alternative.me Fear & Greed API, so the dashboard works the moment it's generated — no signup.

How should I use it?

As a contrarian sentiment gauge: Extreme Fear can flag over-pessimism (possible opportunity) and Extreme Greed possible over-extension. It's context, not a trade signal — pair it with your own strategy.

Can I combine it with other tools?

Yes — ask to add a watchlist, price alerts, or your portfolio next to the gauge, all in the same project.
