What the index measures

The index aggregates several observable market inputs (volatility relative to recent averages, market momentum and volume, social-media activity, Bitcoin's dominance of total crypto market value, and search trends) into one number from 0 (extreme fear) to 100 (extreme greed). None of the inputs is a forecast; each is a reading of how market participants are behaving right now.

Because the components are behavioral, the index is best understood as a crowd-positioning gauge rather than a valuation tool. It says nothing about whether Bitcoin is cheap or expensive; it says how stretched sentiment is in either direction, which matters because stretched sentiment is what reverses.

How to read extremes

The index is a contrarian instrument at its tails. Readings in extreme fear have historically clustered around better forward entry points than readings in extreme greed, for a mechanical reason: extreme fear means sellers have already sold, leverage has been flushed, and marginal bad news finds fewer remaining sellers. Extreme greed is the mirror image: fully invested crowds, elevated leverage, and vulnerability to any disappointment.

The middle of the range carries little signal. A move from 40 to 55 is noise; what our coverage flags is time spent pinned at the extremes, divergences between sentiment and price, and the speed of swings: a violent flip from greed to fear often marks a liquidation cascade rather than a considered repricing.

How we use it

Our crypto desk cites the index as context, never as a standalone signal. It appears alongside harder positioning data (perpetual futures funding rates, options skew, ETF creation and redemption flows) because sentiment gauges are most reliable when they agree with what leveraged money is actually doing. When the index screams fear but funding is still positive and crowded, the flush usually isn't finished; that disagreement is exactly what our daily sentiment pieces are built to catch.

Frequently asked questions

What is the Crypto Fear & Greed Index?expand_more

A daily composite sentiment score from 0 to 100 for the crypto market, primarily Bitcoin. It blends volatility, momentum and volume, social-media activity, Bitcoin dominance and search trends. Zero represents extreme fear (capitulation), one hundred represents extreme greed (euphoria).

Is extreme fear a buy signal?expand_more

Historically, extreme-fear readings have coincided with better forward returns than extreme-greed readings, because panic selling exhausts the pool of remaining sellers. But it is a contrarian context tool, not a timing signal: extreme fear can persist for weeks in a real downtrend, which is why we pair it with funding rates and flow data before drawing conclusions.

How often does the index update?expand_more

The index publishes one reading per day. The value on this page refreshes automatically as each new daily reading is released, and our crypto coverage references the reading on the day each article is written.

Does the index predict Bitcoin's price?expand_more

No. It measures how market participants are behaving, not where price is going. Its value is contrarian and probabilistic: sentiment extremes mark conditions under which reversals become more likely, and it works best combined with positioning data such as ETF flows, futures funding and options skew.
