WhaleScanApril 6, 2026

What is the Fear & Greed Index?

The Fear & Greed Index measures crypto market sentiment on a scale of 0 to 100.

  • 0-24: Extreme Fear — Investors are very anxious

  • 25-44: Fear — Negative market sentiment

  • 45-55: Neutral — Wait-and-see mode

  • 56-74: Greed — Positive market sentiment

It quantifies Warren Buffett's famous advice: "Be greedy when others are fearful, and fearful when others are greedy."

How to Use for Trading

Extreme Fear (0-24)

Paradoxically, this can be a buying opportunity. "Buy when there's blood in the streets." Historical data shows that buying during extreme fear often led to mid-to-long-term profits.

Extreme Greed (75-100)

Market is overheated. New purchases require caution. When Bitcoin exceeded $60K in 2021, the index was above 90 — followed by a 50%+ crash.

Important Note

Don't invest based solely on this index. It's just a reference indicator. Extreme fear can last months, and prices can rise further during extreme greed.

FAQ

Q. Should I always buy when the index is low?

No. Extreme fear can persist for months. Dollar-cost averaging is recommended.

Q. Why do different sites show different numbers?

Calculation methods and data sources differ. Some focus on global markets, others on specific exchanges.

Q. What does an index of 50 mean?

Neutral state. Market has no clear direction and is waiting.

Conclusion

The Fear & Greed Index is a useful tool for gauging market sentiment at a glance. Near 0 = extreme fear (potential buying opportunity), near 100 = extreme greed (caution advised).

However, don't rely on this indicator alone. Use it alongside other analysis tools for informed decisions.
