Reading These Two Together
Fear & Greed measures overall market emotion — extreme fear often shows up near local bottoms (everyone's already sold), extreme greed near local tops (everyone's already in). It's a contrarian-leaning signal, not a timing tool on its own.
Altcoin Season measures something different — whether capital is concentrated in Bitcoin or spread across altcoins. A low reading means Bitcoin is outperforming most of the market (common in early-cycle or risk-off periods); a high reading means altcoins are broadly outperforming Bitcoin (common in late-cycle, risk-on periods).
Together: Fear+Bitcoin Season often marks genuine risk-off periods. Greed+Altcoin Season often marks late-cycle euphoria — historically a stretch worth being more careful in, not less.
