The Bitcoin Fear and Greed Index quantifies investor sentiment, operating on the principle that fear drives Bitcoin prices down while greed propels them upward. This metric aligns with the classic bull (greed-driven) and bear (fear-driven) market analogy, helping traders gauge whether Bitcoin is undervalued or overvalued based on collective market psychology.
