Overall Crypto Market Cap
The total crypto market capitalization is the combined dollar value of all cryptocurrencies (calculated as price × circulating supply for each), serving as a key gauge of the entire sector's size, health, and investor confidence. Rising market caps often signal broad adoption and bull phases, while sharp drops highlight risk-off sentiment or corrections.
• Altcoin Index
The altcoin index (or altcoin season index) tracks the performance of alternative cryptocurrencies relative to Bitcoin, typically showing altcoin dominance or strength when non-BTC coins outperform. That helps new investors spot "altseason" opportunities where capital rotates from Bitcoin into riskier, higher-potential alts for potentially bigger gains (and bigger risks).
• Fear and Greed (Combined with Market Context)
The Fear and Greed Index, when viewed alongside overall market cap and altcoin trends, reveals crowd psychology driving crypto cycles. Extreme fear during market cap crashes often creates undervalued buying windows (especially for alts), while extreme greed during cap surges and alt rallies frequently precedes pullbacks, teaching beginners to stay disciplined amid emotional swings.
