Bitcoin's market dynamics are evolving as institutional participation and liquidity increasingly influence price movements, diverging from the traditional four-year cycle pattern. In the fourth quarter of 2025, Bitcoin experienced a 36% decline from its peak, attributed to early supply absorption through spot ETFs and reduced volatility. Despite this, the fear and greed index indicates a resurgence in risk appetite, with options expiry and macroeconomic factors potentially setting the stage for a rebound. While halvings remain relevant, liquidity and global economic indicators are now the primary drivers of Bitcoin's price action.
