Market sentiment dominates the crypto space. Typically, greed leads to bullish trends, while fear results in bearish trends. Human psychology is predictably irrational, as many people react similarly in certain contexts. Some academics claim that fear and greed can affect people’s brains, causing individuals to set aside common sense and self-control and even invoking change. This is what sentiment analysis attempts to capture: It takes human psychology into account in analyzing the mood of the market. 

Conclusions can then be drawn and evaluated to forecast the course of the price action. An example of such behavior is 

 (fear of missing out), which occurs especially with strong price changes and tempts participants in the market to rash actions.

 tools, such as traded volumes and historical data, can be used to predict price movements. 

If people behave the same way in certain contexts, is it possible to profit simply by being contrarian and behaving differently from others? This is where the Crypto Fear and Greed Index is helpful.

Drawing inspiration from that of the stock market Fear and Greed Index, 

 has developed the Crypto Fear and Greed Index to put general market sentiment into perspective, as fear and greed affect the willingness of investors to pay. The goal is to help traders analyze the market and make informed decisions.

To obtain a meaningful result, the quality of data is crucial. Thus, even small errors can skew or even invalidate an analysis. As a result, faulty decisions and placements in the market can cost a lot of money.

Uncertainty in the entire crypto market can be utilized as a potential opportunity. Often, maximal fear in the market implies the arrival of a bearish trend driving down prices. This could be an ideal time to 

 and, therefore, may be considered a buying opportunity for crypto investors. Likewise, extreme greed in the market could lead to skyrocketing prices — which could be interpreted as the end of a current bullish market and an indication that a correction is due. In that case, selling before the market goes south could be a good idea.

The basis in sentiment analysis is the behavior of the largest crypto exchanges on the market. Often, large price changes happen there first, with other participants in the market subsequently orienting themselves to them. For example, analyzing order books provides an indicator that’s difficult to reproduce in an index, but it can have a major impact on the behavior of traders. The Bybit exchange displays its order books in real time, so that price changes in small time windows can often be weighed against the number of buy and sell orders.

How Does the Fear & Greed Index Work in Crypto?

Theoretically, you can design your own Fear and Greed Index. The prerequisite is that your data is both correct and correctly used. For example, a certain basic knowledge of market events and reactions is necessary in order to realistically assess the effects of certain events. The weighting of individual factors also plays an important role in your analysis.

Different zones on the index chart and slider have different meanings.

This is how the Crypto Fear and Greed Index is measured:

In the index chart, fear (a score between 0 and 49) symbolizes undervaluation of a crypto asset. Greed (50 to 100) implies an overvaluation of cryptocurrencies, and a potential crypto bubble. Every 24 hours, the Crypto Fear and Greed Index is refreshed. To determine its value, we assemble data from six distinct references.

The rating of the Fear and Greed Index for 

 (high volatility) is a sign of an anxious market and reduced risk appetite of investors, while a stable price development means more security. The Fear and Greed Index measures current volatility and compares it to the averages of the last 30 and 90 days. Unusual and strong volatility directly affects prices, potentially leading to chain reactions.

Market momentum refers to the aggregate rate of acceleration of the market, used to measure market sentiment. Market momentum can trend upward or downward, which can be further confirmed by changes in trading volume: The greater the market volume, the more traders who are participating. This can be calculated from the current market volume using the averages of the last 30 or 90 days. The higher the purchase volume in a positive market, the higher the greed.

Likewise, the market volume can be valued by the put/call ratio. The formula is derived by dividing the total number of put options (short positions) by the total number of call options (long positions). If the resulting value is > 1, then put options are predominant, indicating that the majority of participants are evaluating the market according to negative sentiment (i.e., they expect prices to fall).

Social media is a good meeting place for conversations on Bitcoin and cryptocurrency. On Twitter, a strong community continuously observes the market and reacts directly to it. The current market mood can be determined by evaluating the number of tweets that contain specific hashtags related to Bitcoin, along with analyzing the speed and frequency of interaction with such posts in a certain time frame. Greater interest and an increase in interactions are usually signs of heightened greed.

Social media also encourages numerous forms of 

. For instance, online posts may give supposedly valuable information, spurring purchases of a crypto asset and creating FOMO. Once FOMO spreads, hasty buyers will hop on the bandwagon without conducting sufficient research, raising the asset’s value and pumping the market excessively. The manipulators who posted the information can then sell their shares of the asset, significantly lowering its price. Manipulators can then buy the crypto asset again once its price has been lowered, starting the pump-and-dump cycle once again.

 is looking to incorporate Reddit sentiment analysis as a source of social media insight complementary to Twitter. Accordingly, they’re experimenting with an algorithm similar to the one that already exists.

Surveys have accounted for 15% of the Crypto Fear and Greed Index, but are currently 

Surveys directly query the mood of crypto market participants, along with other interested parties. A few credible third-party websites are used to conduct weekly surveys, with sample sizes of 2,000–3,000 people. These surveys help estimate the overall market sentiment, since the selected samples represent groups of crypto traders and investors. 

Advertising campaigns often use this method to present their product in a better light. Justin Sun, the founder of the cryptocurrency platform 

 for using this method to advertise his platform.

In the crypto market, Bitcoin is King. Its dominance is reflected in its share of the total crypto 

 can point to an uncertain market, as many investors shift their investments from risky altcoins to Bitcoin. In this case, Bitcoin is considered a haven, a less risky asset protecting investors from a sharp fall in prices. Alternatively, when the market is greedier, investors turn toward risk-on assets, 

, in the hopes of catching huge returns. This shift in capital results in a declining Bitcoin dominance.

However, this factor can be interpreted very differently, since high levels of investment in Bitcoin can also represent a secure market environment.

It should be noted that the Crypto Fear and Greed Index doesn’t take other crypto assets into account. Given the rise of 

, investors might be flocking to them as a safe haven instead of Bitcoin. Hence, even though Bitcoin dominance may be low, the market still shows bearish signs because investors don’t want to buy into riskier crypto assets.

 is a powerful tool for analyzing users’ interests, making it possible to evaluate Google entries related to specific search terms. For instance, as soon as interest in Bitcoin increases, search queries and prices increase. Historically, increases in Google BTC searches have coincided with dramatic volatility in crypto prices.

Search terms are weighted by both perceived importance and search volume. As such, not all searches are weighted equally: A search for “Bitcoin manipulation” indicates greater levels of fear, and will weigh more heavily toward bearish sentiment. On the other hand, searches such as “How to buy Bitcoin” reflect market demand and interest, contributing to bullish sentiment.

Extreme fear levels in the index have always preceded bullish reversals of crypto prices. At this level, the index shows that prices are low, and the fear of losing capital leads to panic among some investors, who then sell their crypto assets. This in turn pushes prices further down. For savvy traders, this is usually the optimal point at which to buy into the market, given that crypto assets are likely undervalued. The index accurately predicts reversals of crypto price performance. Its measure of pronounced anxiety has often predicted a reversal of crypto prices.

Similarly, extreme greed, usually driven by FOMO, often means that market prices are in the overbought zone, with crypto assets overvalued. This indicates a growing risk of a bursting bubble, with minimal reward for remaining in the market. This is often a signal to either short the market, or sell one’s crypto holdings. Typically, extreme greed precedes a bearish trend.

These findings seem to confirm that pronounced market sentiment is an accurate predictor of a turnaround in crypto prices. Extreme fear in crypto markets has historically morphed into bullish trends, while extreme greed has turned bearish. 

Can You Use the Crypto Fear & Greed Index to Predict the Market?

The Crypto Fear and Greed Index is an excellent indicator for predicting when a local low point in crypto prices has formed, and when a rally could occur. It’s particularly useful when there are new and short-term changes within the market. In the right hands, the index is a valuable tool for timing a change in market sentiment and a subsequent reversal in crypto prices.

The Crypto Fear and Greed Index tends to reverse when it approaches the territory of extreme fear. This is the moment when fear turns into very early signs of greed (before entering into full-blown greed territory).

The Crypto Fear and Greed Index can be a helpful tool for monitoring market sentiment turns. Large fluctuations may present an opportunity to enter or exit before the rest of the market mirrors the trend. 

The index doesn’t work as well for long-term analysis of crypto market periods. Within a long-term bull or bear run, there are recurring rounds of fear and greed. These switches are valuable for swing traders.

There are several factors that the index doesn’t take into account. First, specific sectors that have shown rapid expansion, such as stablecoins and DeFi, aren’t considered. Second, the index doesn’t take 

 (ETH), the second-largest asset in crypto, into consideration. And lastly, Bitcoin halving isn’t factored into the index, despite its potential to effect significant bullish sentiment with its huge reduction in supply and reduced inflation rate.

Since the above-mentioned factors aren’t used in calculating the Crypto Fear and Greed Index — despite their potential impact on market sentiment — other tools should be used, in addition to the index, for the purpose of crypto market prediction.

Although the Crypto Fear and Greed Index can be a very important and helpful tool in assessing the market sentiment revolving around a crypto asset, it should never stand alone. Using a single indicator isn’t sufficient to make an informed decision. Various factors play a role in pricing, and should always be considered. 

For example, the Fear and Greed Index refers only to sentiment analysis, while technical analysis and 

 work independently of market participants’ emotions. However, keep in mind that some new financial or geopolitical events may void any analysis.
