According to @BullTheoryio, Bitcoin has broken its traditional 4-year halving cycle as the post-halving year 2025 closed red, the first such occurrence in 14 years, source: @BullTheoryio, Jan 1, 2026. Historical pattern described by the source indicated halving years usually closed green, so this red close represents a clear deviation from prior cycles, source: @BullTheoryio, Jan 1, 2026. Trading takeaway: cycle-based seasonality signals for BTC should be treated with caution and strategies relying on the four-year halving model may require reassessment of timing, risk, and exposure, source: @BullTheoryio, Jan 1, 2026.
