- • Market Momentum: Volume and price momentum

- • Surveys: Investor sentiment polls
- • Dominance: Bitcoin's market cap dominance
- • Trends: Google search trends for Bitcoin

Bitcoin-specific market sentiment indicator
Yes — the Fear & Greed Index you're referring to from alternative.me is specifically for Bitcoin, not the broader crypto market (although Bitcoin tends to influence overall market sentiment).
🔍 How Is It Calculated?
The index is a composite score where:
🔍 Breakdown of the Components:
Each metric is assigned a weight (not publicly disclosed in detail, but this is their general breakdown):
Compares BTC's current volatility to the average of the last 30 and 90 days. Sharp spikes = fear.
Measures trading volume and market momentum. High buying volumes = greed.
Reddit and Twitter mentions, hashtags, engagement spikes = greed/fear.
If BTC dominance is rising, it suggests fear (people exiting altcoins for BTC). Falling = greed (more altcoin risk).
Searches like "Bitcoin crash" = fear, "Bitcoin price prediction" = greed.
Occasionally used (but discontinued for now) — sentiment from public polls.
✅ Example Interpretation:
It's not a crystal ball but it's widely used by traders to gauge market psychology.

Everyone's euphoric, overbought conditions
