FAQ

What is the Bitcoin Fear & Greed Index?

A market sentiment indicator scored from 0 (Extreme Fear) to 100 (Extreme Greed). It combines volatility, market momentum, social media sentiment, Bitcoin dominance, and Google Trends into a single daily number that reflects how investors are feeling about Bitcoin.

Should I buy Bitcoin when the index shows Extreme Fear?

Historically, periods of extreme fear have often preceded price recoveries — following Warren Buffett's principle of being "greedy when others are fearful." However, the index is a sentiment tool, not a crystal ball. It doesn't predict price direction and shouldn't be your only reason to buy or sell.

How often is the index updated?

Once per day. The index aggregates data from multiple sources and produces a new reading each day. The exact update time varies but typically occurs in the early hours UTC.

Is the Fear & Greed Index reliable?

It's a useful directional signal, not a trading indicator. It captures crowd psychology well — extreme readings have historically aligned with market turning points. But it's backward-looking by design: it tells you how people feel now, not where price goes next.
