What is Crypto Fear and Greed Index?

To feel the pulse of the market, crypto traders usually rely on three very important ways of analysis. One is fundamental knowledge about the asset. Second is the technical analysis. It is fairly detailed, full of mathematical calculations and quite complicated to understand. The last one in the mix is sentimental analysis. This type of analysis is much simpler to understand as it depends on the market reaction to the news and overall situation of the crypto world. Crypto Fear and Greed Index can be considered as a tool to measure the impact of top influencers tweets. How do people react to Elon Musk’s latest tweet about Dogecoin, for example? Is it turning the tide in a positive or negative direction? Pretty difficult to gauge without the right tool. This is exactly where Crypto Fear and Greed Index comes in. It is a sentimental analysis tool, used to measure the current state of the market in terms of traders’ emotional reaction. 

To begin understanding the Crypto Fear and Greed Index, it is important to know what makes it a necessary tool. The index provides an insight into the general feeling of the market. When the index is showing a high value, it means that the investors feel confident and are buying more. However, if the index shows a lower value, it is possible that investors feel scared and there is more of a selling sentiment across markets. 

The values are measured from 0-100. Lower scores represent fear and higher scores represent greed. 

  • A value of 0-24 represents “extreme fear,” meaning that investors are selling and exiting the market. 
  • The range of 25-49 represents “fear”. This could mean that a fair amount of investors are selling and market interest remains neutral. 
  • A value of 50-74  represents “greed,” meaning that there is a decent amount of buying. It could lead to a rise in prices. 
  • Value from 75 to 100 represents “extreme greed”. This value indicates an extremely volatile  market and the potential for a market “bubble”.

How is the Crypto Fear and Greed Index Calculated?

To calculate the market sentiment and give out the crypto fear and greed index value, data analytics platforms use the following measures: 

  • Volatility: When the market becomes more volatile, it is possible that the fear factor rises. In the example of bitcoin, the index measures the maximum drawdowns of bitcoin and compares it with the corresponding average values of the preceding 30 days and 90 days. 
  • Social Media: Platforms like Twitter, Facebook, Instagram, Reddit and Telegram are active hotspots of conversation around crypto. On such platforms, data is gathered and posts with various hashtags for each coin are counted. It is also important to check how frequent or fast these interactions are taking place to determine how ‘active’ they are. When there is an unusually high positive interaction around a coin, it means that the market is moving towards a more greedy phase. 
  • Momentum/Volume: For giving the final index value it is important to measure the current volume and market momentum. When the buying volumes are higher than the overall momentum, it could be considered that the market is getting greedy. 
  • Surveys: Many data analytics platforms collect trader insight data which include polls and surveys about their perspective on the market. This helps them get a picture of the sentiment of a group of crypto investors. 
  • Dominance: In the case of Bitcoin, the rise in the dominance of the coin is considered indicative of the speculation around altcoin investments. If Bitcoin dominance goes lower, people might be getting more greedy and risk-taking in terms of altcoin investments.
  • Trends: Google trends and search data is key in understanding the focus of the traders and investors. If there is a large search volume under the cryptocurrency topic and specific keywords related to coins, it could be indicative of growth or decline of interest. However, based on specific search terms it is easy to spot whether the market is turning towards fear or greed.
