According to Michaël van de Poppe, the widely referenced Bitcoin BTC four-year halving cycle may be misleading, and he released a new video update to reassess whether the cycle still exists and what the setup into 2026 could mean for traders (source: Michaël van de Poppe on X, Nov 13, 2025, linking to a YouTube update). His post explicitly asks whether the 4-year cycle is still alive, whether it exists at all, and what 2026 might bring, signaling caution for cycle-based timing strategies and encouraging traders to review his analysis before positioning (source: Michaël van de Poppe on X, Nov 13, 2025).
