The Fear And Greed Index is an indicator designed to measure market sentiment, particularly the emotions of fear and greed among investors. This index analyzes various emotional factors in the market to help investors understand whether the current market sentiment is overly optimistic (greedy) or overly pessimistic (fearful), thereby providing a reference for investment decisions.

The Fear And Greed Index utilizes a straightforward scale ranging from 0 to 100. It can be broken down into three categories of the market sentiment:

0-40: Fear

40-60: Neutral

60-100: Greed

When the index approaches zero, it signifies extreme fear, which may indicate that many Bitcoin ($BTC) and cryptocurrency investors are overly concerned about further price declines. At this point, market sentiment is highly fearful, and Bitcoin may be undervalued, presenting a potential buying opportunity.

Conversely, when the index nears 100, it indicates extreme greed, suggesting that many Bitcoin ($BTC) and cryptocurrency investors are overly excited about the prospect of further price increases. This implies that Bitcoin's price is significantly above its intrinsic value, making it a potentially opportune time to sell.

The indicator reliability between Bitcoin’s price and the Fear and Greed Index ranges from 0 to 1. Based on regression model tests conducted by the RightPulse Lab, the closer the indicator reliability value is to 1, the more reliable this indicator becomes for decision-making..
