What is the Fear & Greed Index?
The Fear & Greed Index is a tool that measures investor sentiment in the cryptocurrency market. It uses a scale from 0 (Extreme Fear) to 100 (Extreme Greed). A lower score suggests that investors are worried and may be panic-selling. A higher score suggests excessive optimism and possibly irrational buying behavior. The index is commonly used to gauge emotional extremes in crypto investing.

So, when the greedy index drops to zero, is it still necessary to log in? What should be the transaction based on?
