【Abstract】This study examines the relationship between investor sentiment and market dynamics across the five largest cryptocurrencies Bitcoin, Ethereum, Binance Coin, Ripple, and Cardano. Using the Crypto Fear & Greed Index as a proxy for market sentiment, we apply wavelet coherence to investigate the co-movement between sentiment and cryptocurrency returns across time and frequency domains. In parallel, impulse response functions from a vector autoregression framework are employed to assess how return shocks particularly in Bitcoin propagate through financial uncertainty, subsequently influencing sentiment and trading activity. Our findings reveal that sentiment functions as a robust leading indicator within an investment horizon of one week to one month, during which notable shifts in trading volume are observed. These results enhance our understanding of sentiment-driven behavior in crypto markets and provide actionable insights for short-term forecasting and investment strategy design across different time horizons.
