What Is the Fear & Greed Index?

Crypto market behavior is highly emotional. When the market rises, people tend to become greedy, leading to FOMO (Fear Of Missing Out). During downturns, irrational selling pressure can take hold.

The index analyzes the current sentiment of the Bitcoin market and distills it into a simple metric from 0 to 100. Zero means "Extreme Fear" and 100 means "Extreme Greed."
