It quantifies investor emotions on a scale from 0 (extreme fear) to 100 (extreme greed), synthesizing data from volatility, trading volume, social media activity, and market trends. This index helps traders identify potential market extremes—whether driven by panic or overconfidence.

How to Interpret the Index for Bitcoin
- Fear (0–49): Suggests investor caution, often coinciding with undervalued prices. Historically, prolonged fear phases have preceded bullish reversals.
- Greed (51–100): Indicates euphoria, potentially signaling overbought conditions. Extreme greed (>75) frequently precedes market corrections.
Example: A reading of 30 ("fear") during a price dip may highlight a buying opportunity, while 80+ ("extreme greed") could warn of overheating.
Strengths of the Index

5. How accurate is social media data?
Twitter trends provide timely signals but can be noisy. Cross-verify with surveys or trading volume.
