Crypto's seasonal trends (e.g., "January Effect," Q4 rallies) have weakened in 2024 due to macro dominance. While Bitcoin halvings (April 2024) still drive cyclicality, Fed policy and ETF inflows now overshadow calendar patterns.  

Historically strong periods (like December gains) faltered as institutional players—less influenced by retail seasonality—dominated flows. Memecoin manias and geopolitical shocks further disrupted typical cycles.  

However, some remnants persist: summer lulls (low volatility) and post-halving surges remain observable, though less predictable. The maturation of derivatives (options expiry cycles) now adds artificial seasonality. In short, macro and structural shifts have diluted—but not erased—crypto's seasonal tendencies. (140 words)
