Track real-time crypto market sentiment. Our Crypto Fear & Greed Index combines Bitcoin trend, RSI, BTC dominance, volume and volatility into a single 0-100 score, updated daily.
Very pessimistic sentiment. Capitulation-level selling.
Cautious sentiment. Investors seeking safety.
Balanced sentiment. No clear trend.
Optimistic sentiment. Investors taking risks.
Market euphoria. Stretched, one-sided optimism.
The Crypto Index measures sentiment towards crypto using 5 components. Calibrated against Alternative.me's philosophy. Focuses on behavioral indicators, volume dynamics, and volatility rather than raw price alone. All scores from 0-100:
30-day BTC price trend (PRIMARY INDICATOR)
Highest weight component. Captures the medium-term trend that drives overall sentiment. Score = 50 + (30-day change x 2.0), capped 0-100. Bitcoin +25% over 30 days = score 100 (extreme greed). Bitcoin -25% = score 0 (extreme fear). Centered at 50 (neutral) with full range 0-100.
Bitcoin technical momentum
Combines RSI directly as a 0-100 score (60% weight) with MA position (40% weight). RSI below 30 = extreme fear, RSI above 70 = extreme greed. Moving average position provides trend context: price above both MA50 and MA200 signals bull market confidence, while price below both MAs indicates bear market fear.
BTC vs ETH performance (inverted)
Tracks relative performance between Bitcoin (digital gold) and Ethereum (altcoin proxy) with a x3.0 multiplier centered at 50. INVERTED logic: When Bitcoin outperforms Ethereum, investors are rotating TO safety (BTC) FROM risk (alts) = fear = lower score. When Ethereum outperforms Bitcoin, "altcoin season" = risk appetite = greed = higher score.
7-day vs 30-day average volume, direction-adjusted
Price-independent signal measuring trading activity dynamics. Compares 7-day average volume to 30-day average, then adjusts for price direction with a x50 multiplier. High volume + rising price = greed (buying pressure). High volume + falling price = fear (panic selling). Low volume = neutral.
14-day annualized volatility (inverted)
Crypto's wild price swings reveal market psychology with thresholds calibrated for crypto: Volatility ≥ 80% annualized = score 0 (extreme fear). Volatility ≤ 25% = score 100 (calm confidence). Between 25-80%: linear interpolation. These thresholds reflect crypto's naturally higher volatility compared to traditional assets.

The Crypto Fear & Greed Index uses 5 components: Context/30-day BTC trend (30%), RSI & Moving Averages (20%), Bitcoin Dominance vs ETH (20%), Volume Trend (15%), and Volatility (15%). It measures sentiment towards crypto using behavioral indicators, volume dynamics, and volatility.
Bitcoin Dominance uses inverted logic: when BTC outperforms ETH, investors are rotating to safety (BTC as digital gold) = fear. When ETH outperforms BTC, it signals altcoin season and risk appetite = greed. This component contributes 20% with a x3.0 multiplier.
No. While inspired by Alternative.me's philosophy, OnOff.Markets uses different components and fully transparent calculations. We focus on price-independent signals like direction-adjusted volume and use crypto-specific volatility thresholds (40-80% vs traditional 20-40%). All formulas are published.
