The Crypto Fear and Greed Index Explained, and How to Use It

The Crypto Fear and Greed Index squeezes the mood of the whole market into one number between 0 and 100. Low numbers mean investors are scared. High numbers mean they are greedy. You can check today's Fear and Greed score on our live index page.

This guide explains what goes into the index, what each zone means, how traders use it, and where it falls short.

What is the Crypto Fear and Greed Index?

The best-known version is published daily by Alternative.me and is built mainly around Bitcoin. The idea is borrowed from a famous line from Warren Buffett: be fearful when others are greedy, and greedy when others are fearful. Crowds tend to sell in panic near bottoms and buy in excitement near tops. The index tries to measure that emotion so you can see it instead of feeling it.

What goes into the index

The score combines several data sources, each given a different weight:

• Volatility. Sudden, large price swings compared with recent averages are read as fear.
• Market momentum and volume. Strong buying volume in a rising market is read as greed.
• Social media. How much, and how positively, people are posting about Bitcoin.
• Bitcoin dominance. When Bitcoin's share of the total market rises, money is often moving to safety, which points to fear. When altcoins take a bigger share, investors are taking more risk.
• Search trends. Spikes in searches such as "bitcoin price manipulation" can signal fear.

Surveys have been part of the formula in the past but have been paused at times, so the exact mix can change.

What each score means

• 0 to 24: Extreme fear. Panic selling, bad headlines, people leaving the market.
• 25 to 49: Fear. Caution, falling or sideways prices.
• Around 50: Neutral. No strong emotion either way.
• 51 to 74: Greed. Rising prices, growing confidence.
• 75 to 100: Extreme greed. Euphoria, fear of missing out, everyone talking about crypto.

How traders use the Fear and Greed Index

As a contrarian signal

The classic use is to go against the crowd. Long periods of extreme fear have often lined up with good long-term buying areas, while extreme greed has often appeared near local tops. A long-term investor might add to a position during extreme fear and take some profit during extreme greed.

As a check on your own emotions

If you feel a strong urge to buy and the index reads 85, that is a reminder that the whole market feels the same way. If you want to sell everything and the index reads 10, the same applies. The number helps you pause before acting on a feeling.

Alongside a plan, not instead of one

Some investors use the index to adjust a regular buying plan, known as dollar-cost averaging. For example, buying a little more each week when the index is in fear, and a little less when it is in greed.

Past examples

• March 2020. During the COVID crash the index fell into single digits as Bitcoin briefly dropped below $4,000. Within a year the price was many times higher.
• Late 2021. The index sat in greed and extreme greed as Bitcoin reached its then all-time high near $69,000, before a long decline.
• Mid 2022. After the collapse of Terra and Luna, the index stayed in extreme fear for weeks while prices kept falling.

The 2022 example matters: extreme fear can last a long time, and prices can keep falling while it does.

The limits of the index

• It is not a timing tool. Extreme fear can get more extreme. Buying the first day of fear is rarely the bottom.
• It lags. Much of the data reacts to price moves that already happened.
• It is Bitcoin-focused. A single altcoin can behave very differently from the score.
• It is one number. It says nothing about news, regulation or the wider economy.

Use it as one input next to price, trend and your own risk rules, never on its own.

Frequently asked questions

Is the Fear and Greed Index accurate?

It accurately reflects the data it measures, but it does not predict prices. Treat it as a mood gauge, not a forecast.

Is extreme fear a good time to buy crypto?
