Why Measure Fear and Greed in the Market?

The cryptocurrency market is highly volatile and it can be said that it is also highly emotional. The two opposing emotions within the market are Fear and Greed.

Investors and traders tend to be increasingly greedy when the market is rising (FOMO). When the market is falling, fear sets in. This index is intended to indicate the current market sentiment for the cryptocurrency market.

The Fear and Greed Index makes two simple assumptions:

  • Extreme fear can be an indication of a buying opportunity.
  • Extreme greed can be an indication of an upcoming market correction.

The current sentiment of the Bitcoin market is determined by crunching the numbers on a simple scale of 0 to 100. Near Zero means refers to "Extreme Fear", while near 100 referred to "Extreme Greed".


Data Sources

The Crypto Fear and Greed Index comes from alternative.me and the team that has generated this index uses primarily five different variables to determine the Fear and Greed index.

This fear and Greed index relates primarily to the market sentiment for Bitcoin, but since Bitcoin continues to hold market dominance, it can also be used as a reflection of the cryptocurrency market as a whole.

Volatility (~25 % of calculation)

Market volatility is an important indicator and represents up to 25% of the weight used in this calculation. Market volatility is compared with the last 30 and 90-day historical values to determine this value. The increase in volatility is an indication of a fearful market.

Market Momentum/Volume (~25% of calculation)

The market volume and momentum are also taken into account for this calculation, using the last 30/90 days as a comparison. Using these historic values the market momentum is determined. Increased buying volume moves the needle closer to the greedy/bullish indication, while decreased volume indicates the opposite.

Social Media (~15% of calculation)

Social media and the positive or negative posts with respect to the market can offer an important indication of the market sentiment. The market sentiment is largely collected from Twitter using hashtags for each of the top cryptocurrencies traded.

Dominance (~10% of calculation)

Bitcoin is the dominant cryptocurrency and as a result, where Bitcoin goes, the market follows. The dominance of a coin is determined by its market capitalization as a percentage of the whole cryptocurrency market. A rise in Bitcoin dominance can be an indication of fear and the decrease in Bitcoin dominance (buying more altcoins) can be a reflection of a more speculative and optimistic outlook on the market.

Google Trends data is pulled for popular Bitcoin-related search queries. The results of these queries are used to determine the trends variable in the calculation.


The Crypto Fear & Greed Index is loosely based on CNN Business's website which has its own Fear & Greed Index, pertaining specifically to the stock market.

The Fear and Greed Index was originally developed by CNN Business to measure the two primary emotions which drive and influence investors - Fear and Greed.

Their index is measured in daily, weekly, monthly and yearly timeframes and can be used to determine if the stock market is fairly priced.  According to CNN Business, they use seven indicators to determine their index, specifically: market momentum, market volatility, safe haven demand, junk bond demand, put and call options and stock price breadth and stock price strength.
