Frequently Asked Questions
Q. How is the Fear & Greed Index calculated?
Alternative.me calculates it using 6 weighted factors: Volatility (25%), Market Momentum/Volume (25%), Social Media (15%), Surveys (15%), Bitcoin Dominance (10%), and Google Trends (10%).
Q. Does buying in Extreme Fear always produce profits?
Historically, long-term buying in Extreme Fear (0-20) has produced strong returns, but short-term further declines are always possible. Dollar-cost averaging (DCA) is the commonly recommended approach.
Q. What should I do in Extreme Greed?
Extreme Greed (80-100) historically precedes corrections. Rather than selling everything, partial profit-taking or tightening stop-losses is generally advised.
Q. How often is the index updated?
The Alternative.me API updates once daily at 00:00 UTC. It is a daily sentiment indicator, not a real-time price feed.
Q. What are the red (20) and blue (80) reference lines in the chart?
The red line at 20 marks the Extreme Fear/Fear boundary, and the blue line at 80 marks the Greed/Extreme Greed boundary — useful decision reference levels.
Q. Does it apply to altcoins as well?
Yes — the index reflects overall crypto market sentiment. It correlates with major altcoins like Ethereum, though project-specific risks are not reflected.
Q. Can I make investment decisions based solely on this index?
No. The Fear & Greed Index is a supplementary indicator only. Combine it with on-chain data, technical analysis, and macro factors. This tool does not provide financial advice.

Expert Knowledge: Crypto Fear & Greed Index — 90-Day History & BTC Buy Timing
The Fear & Greed Index was originally developed by CNN Money for equity markets and adapted for crypto by Alternative.me in 2018. Since then, it has shown strong correlation with Bitcoin market cycles.
Warren Buffett's famous principle — "Be greedy when others are fearful, be fearful when others are greedy" — is exactly what this index quantifies. Readings below 10 in December 2018 (crypto winter), March 2020 (COVID crash), and June 2022 (Terra-Luna fallout) all proved to be exceptional long-term entry points in hindsight.
However, extreme fear caused by structural events (exchange failures, regulatory shock) can precede further declines. Always cross-check with on-chain metrics like MVRV and SOPR, as well as broader macro conditions, before making investment decisions.
