Debate Over Bitcoin's Four-Year Cycle Amid ETF Influence

According to Odaily, the validity of Bitcoin's four-year cycle has once again become a central topic within the ecosystem. Some argue that the cycle should not extend to 2026 due to the $57 billion inflow into ETFs. However, opposing views maintain that the cycle remains intact, with historical coincidences supporting this perspective. For instance, Bitcoin's recent local bottom occurred on November 21, 2025, at a price of $80,524, mirroring the previous cycle's low on November 21, 2022, at $15,460, with both dates being identical. Currently, market attention is shifting towards January 2026, when a U.S. crypto market structure bill is scheduled for a hearing on January 15. This event is seen as a potential significant turning point in the current Bitcoin cycle.
