Crypto Fear & Greed index explained

The Fear & Greed index compresses the mood of the crypto market into one number from 0 to 100. Here is what goes into it, how people use it, and the easiest way to keep it in view.

What the index measures

The Crypto Fear & Greed index, published daily by alternative.me, combines several market signals into a single score:

  • Volatility — unusually large moves push the score toward fear.
  • Momentum and volume — strong buying volume in an uptrend reads as greed.
  • Social media — activity and sentiment around major coins.
  • Bitcoin dominance — a rising BTC share of the market is often read as a flight to safety.
  • Search trends — spikes in searches for crypto terms.

The result is a number and a label:

ScoreLabelTypical reading
0–24Extreme fearPanic selling, capitulation
25–44FearCautious, defensive
45–55NeutralNo strong bias
56–75GreedOptimism, rising leverage
76–100Extreme greedEuphoria, FOMO

How people use it

The index is a contrarian sentiment gauge, not a prediction. The common reading is Warren Buffett’s line turned into a dial: extreme fear can mark moments when others are over-selling, and extreme greed can mark moments when the market is over-extended. Most people use it as context for a decision they were already considering — a reason to slow down when the dial is pinned at greed, or to look more closely when it is pinned at fear — rather than as a signal on its own.

What it is not

It is a daily snapshot of Bitcoin-centric sentiment. It does not know about your altcoin, it lags fast moves, and it has stayed in “extreme greed” for weeks during strong bull runs. Treat it as a weather report, not a forecast.
