FAQ

What is the Bitcoin Fear & Greed Index?

A daily sentiment score from 0 (Extreme Fear) to 100 (Extreme Greed). It blends volatility, trading momentum, social media activity, Bitcoin dominance, and Google Trends into one number that captures how the market feels about Bitcoin right now.

Should I buy Bitcoin when the index shows Extreme Fear?

Extreme Fear readings have often lined up with price bottoms in the past. But the index reads crowd mood, not future price. Use it as one data point alongside your own research, not as a standalone buy or sell signal.

How often is the index updated?

Once per day. A new reading drops each morning, usually in the early hours UTC. The exact time varies slightly.

Is the Fear & Greed Index reliable?

It reads crowd psychology well. Extreme readings have often coincided with turning points in the past. But the index looks backward by design: it tells you how traders feel today, not where price goes tomorrow.
