January's opening weeks could be a critical inflection point for bitcoin. We're about to find out whether the widely-discussed 4-year cycle—a pattern that's historically aligned with halving events and major price movements—still governs BTC's market dynamics. Traders and analysts have long tracked this cycle as a potential roadmap for price behavior, but market conditions keep evolving. The data coming in over these crucial first two weeks could either validate the cycle thesis or suggest the market has fundamentally shifted. Keep a close eye on volume, volatility, and key price levels during this window.
