  • From 0 to 49 represents Fear.
  • From 51 to 100 represents Greed
  • 50 represents a neutral market.

However, if broken down more closely, the colors on the chart have the following meanings:

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

Fear means the market is showing bad signs, most token values decrease and people tend to sell everything. In contrast, a greedy market shows signs of “FOMO”, that means people buy everything because token prices increase everyday.

How accurate is Fear and Greed index in Crypto?

Although Fear and Greed Index has a high accuracy, we should not totally depend on this index. To make great trading decisions, analysts often combine various indicators such as chart analysis, the on-chain data of BTC, ETH to see the general sentiment, the on-chain data of a specific asset,…

Because the Fear and Greed Index shows the general market situation and updates very slowly, it only provides an overview of the market, suitable for long-term players. If you are short-term traders, this indicator is not really necessary.

In addition, there is no data to show how much Fear and Greed index is going to change in the market. Which means we all know when the market is greedy, there will be a time of strong correction. The problem is how much Fear and Greed Index will change? That's something we don't know. So Fear and Greed Index is not used to help determine when the market corrects.

Also, in a Bull or Bear market, sometimes we still see the indicator showing the opposite side. However, that doesn't mean the market has ended its trend and changed direction. It could be a small correction to establish a more sustainable big up/down trend.

To sum up

The Fear & Greed Index is an indicator that is, although not totally exacting, perhaps one of the most interesting as it describes the general mood of the market at a given time. This helps users in getting a general view of the market. However, we need to consider other factors to make the right investment decision.
