What You Need to Know About the Crypto Fear and Greed Index

The Fear and Greed Index is a tool that measures market sentiment in the crypto industry, assigning a score from 0 to 100 that reflects investors' prevailing emotions. Fear represents scores from 0 to 49, indicating undervaluation and an excess supply of cryptocurrencies, while scores from 50 to 100 represent greed, suggesting overvaluation and the potential presence of a market bubble. Monitoring changes in fear and greed levels can be beneficial when formulating a trading strategy for entering or exiting the crypto market, providing investors with insights into the overall sentiment and opportunities to make well-informed decisions.


When making trading decisions in the crypto market, it is crucial for traders and investors to base their choices on reliable data. While there are various factors to consider, such as charts, fundamentals, and market sentiment, studying every available metric and index can be time-consuming and inefficient. That's where the Crypto Fear and Greed Index comes in.

The Crypto Fear and Greed Index combines sentiment and fundamental metrics to offer insights into market fear and greed. While it shouldn't be the sole indicator for decision-making, it can provide a glimpse into the overall sentiment of the cryptocurrency markets. By utilizing this index alongside other relevant factors, traders and investors can gain a better understanding of the market's general sentiment and make more informed choices.

What Is an Index?

The Crypto Fear and Greed Index measures market sentiment in the crypto industry. It assigns a score from 0 to 100, reflecting the prevailing emotions among investors. Unlike traditional indices like the Dow Jones Industrial Average (DJIA), the Crypto Fear and Greed Index is not a purchasable financial instrument. It serves as a market indicator rather than a tradable asset and is a weighted measure of market data that can be used to complement your analysis of the crypto market. By considering the Crypto Fear and Greed Index alongside other relevant information, traders and investors can enhance their understanding of market sentiment.

What Is a Market Indicator?

Market indicators are valuable tools for traders and investors to analyze market data. They exist in different forms of market analysis, including technical, fundamental, and sentiment analysis. Technical indicators, such as moving averages and chart patterns, focus on price and volume trends. Fundamental indicators assess the underlying value of a project based on factors like user count and market value.

Market sentiment indicators measure the feelings of investors and traders. Examples include the Crypto Fear and Greed Index, The Bull & Bear Index from Augmento, and WhaleAlert, which tracks large transfers in crypto markets. Sentiment analysis is particularly useful in the cryptocurrency space, where social media and public opinion play significant roles.

How Does the Fear and Greed Index Work?

The Fear and Greed Index was initially developed by CNNMoney to assess market sentiment in stocks and shares. The Crypto Fear and Greed Index examines various market indicators and trends to determine whether market participants are driven by greed or fear. A score of 0 represents extreme fear, while 100 indicates extreme greed. A score of 50 suggests a relatively neutral market sentiment.

When the market is fearful, it may indicate that cryptocurrencies are undervalued. However, excessive fear can lead to panic selling and market turmoil. It's important to note that fear alone does not necessarily indicate a long-term bearish trend. Instead, it serves as a reference for short to mid-term market sentiment.

Conversely, greed in the market signifies the opposite situation. If investors and traders exhibit greed, there is a risk of overvaluation and a potential market bubble. For instance, when FOMO (Fear of Missing Out) drives investors to inflate the market, the price of Bitcoin can become artificially inflated due to excessive demand.


The Crypto Fear and Greed Index currently focuses solely on Bitcoin-related data. This decision is based on Bitcoin's strong correlation with the overall crypto market in terms of price and sentiment. However, there are future plans to expand the index's coverage to include other major coins, such as Ether (ETH) and BNB.

The index's scale is divided into four categories:

  • 0-24: Extreme fear (orange)
  • 25-49: Fear (amber/yellow)
  • 50-74: Greed (light green)
  • 75-100: Extreme greed (green)

To calculate the index value, five different market factors are combined using specific weights.

  1. Volatility (25% of the index): This factor assesses the uncertainty in the market by measuring Bitcoin's current value compared to the averages of the past 30 and 90 days.
  2. Market momentum/volume (25% of the index): By comparing Bitcoin's current trading volume and market momentum with the average values of the previous 30 and 90 days, this factor gauges market sentiment. Consistent high-volume buying indicates positive or greedy sentiment.
  3. Social media (15% of the index): This factor analyzes the number of Twitter hashtags related to Bitcoin and measures its interaction rate. A constant and unusually high level of interactions indicates more market greed than fear.
  4. Bitcoin dominance (10% of the index): This factor determines the dominance of BTC in the market. An increase in Bitcoin dominance suggests new investments in the coin and the potential reallocation of funds from altcoins.
  5. Google Trends (10% of the index): By examining Google Trends data for Bitcoin-related search queries, this factor provides insights into market sentiment. For example, a rise in searches related to "Bitcoin Scam" would indicate higher fear in the market.
  6. Survey results (15% of the index): Currently paused, this input has been inactive for some time.

Is It Suitable for Long-Term Analysis?

The Crypto Fear and Greed Index is not as effective for long-term analysis of crypto market cycles. It's more suitable for swing traders who can benefit from the shifts between fear and greed within bull or bear runs. However, for investors looking to hold their positions, relying solely on the index to predict the transition from a bull to a bear market would be challenging. To gain a comprehensive long-term perspective, it is necessary to analyze other aspects of the market. It is advised not to rely solely on a single indicator or analysis method. It is crucial to conduct your own research before investing and only invest funds that you can afford to lose.


The Crypto Fear and Greed Index simplifies the process of gathering and summarizing various fundamental and market sentiment metrics. Instead of manually collecting this data, the indicator tracks social media, Google Trends, and other statistics for you. If you choose to use the index in your analysis, it is advisable to combine it with other metrics and indicators to obtain a more comprehensive and well-rounded perspective.
