One number for the market's mood, from 0 (extreme fear) to 100 (extreme greed) — built from volatility, momentum, volume, social buzz and BTC dominance.
It measures the emotion driving the crypto market by combining volatility, momentum, volume, social media and Bitcoin dominance into a single 0–100 score. Low numbers mean panic; high numbers mean euphoria.
Extremes often mark turning points — extreme fear can signal a market that's oversold (historically a zone where patient buyers did well), while extreme greed warns the market may be due for a pullback. Warren Buffett's line applies: "be fearful when others are greedy, and greedy when others are fearful."
It's one signal among many, not a timing tool on its own — markets can stay fearful or greedy for weeks. Pair it with the Screener, the live liquidations feed and your own plan in Paper Trade.
Historically, extreme fear (0–25) has marked oversold zones where patient buyers did well — but sentiment can stay depressed for weeks, so treat it as context, never a buy signal on its own. If you want to act on a zone, test the idea risk-free in Paper Trade first.
Extreme greed (76–100) means euphoria is driving price and a pullback becomes more likely. That's when traders tighten stops, take partial profits or cut leverage — you can check how crowded the market is on the long/short ratio and funding rates pages.
