Can the four-year cycle still be trusted? Bitcoin will face its biggest test in January 2026.

Bitcoin’s four-year cycle theory is facing a real test from the market. This once infallible pattern encountered an unprecedented challenge in January 2026. Supporters point to the astonishing coincidence of dates and timing, while skeptics argue that institutional participation has fundamentally changed the game. Currently, BTC is hovering around $91,010, and the U.S. cryptocurrency bill will be reviewed on January 15th. Market focus has shifted to whether this month will once again serve as a critical inflection point in Bitcoin’s cycle.

The “Curse” of Cycle Theory and Its Clash with Reality

Supporters: The coincidence of timing and data is too far-fetched

Bitcoin’s four-year cycle is closely linked to the halving mechanism. Historical data shows this pattern has been quite accurate. After the April 2024 halving, Bitcoin reached a high of $126,000 about 18 months later (October 2025), followed by a local low of $80,524 on November 21, 2025.

Most intriguing is the overlap of dates. The local low on November 21, 2025, coincides exactly with the low point of the previous cycle, which occurred on November 21, 2022, at a price of $15,460. The same date, exactly three years apart—such a coincidence is hard to explain with probability alone.

From the $15,500 low in November 2022 to the $126,000 high in October 2025, the increase exceeds 8 times. This rhythm aligns highly with historical cycles, indicating that supply-demand changes driven by halving are still at play.

Additionally, January has repeatedly been a key month in recent cycles. In January 2023, a local high was formed near $25,000; in January 2024, after the launch of the US spot Bitcoin ETF, prices dipped to the year’s lows; and in January 2025, amid Trump’s inauguration, prices approached $110,000. The repeated appearance of these time points suggests some structural significance to January.

Skeptics: Market structure has fundamentally changed

But opponents have stronger arguments. The US spot Bitcoin ETF has accumulated about $57 billion in funds, and the depth and breadth of institutional participation are no longer comparable to the past. This has altered the price discovery process—no longer a game between retail investors and miners, but a combined effect of institutional capital and policy.

Companies like MicroStrategy have formed structural buy orders, creating demand curves that conflict with the natural halving cycle. Meanwhile, early Bitcoin holders have been cashing out at high levels above $100,000, which is completely different from the “retail FOMO” pattern seen in previous cycles.

More critically, traditional cycle projections would suggest a parabolic top in 2025, but the actual market has shown more oscillation and retracement. This indicates a shift in market dynamics. Gemini’s institutional business director Patrick Liou even stated that the four-year cycle of Bitcoin has ended, with market maturity leading to significantly reduced volatility.

The True Reflection of the Current Market Structure

From related news, subtle changes are indeed occurring in the market. MARA transferred 519.46 BTC (worth $48.3 million) to FalconX; MicroStrategy, although restarting acquisitions of 1,287 BTC (worth $118 million) in early January, has seen its financing costs rise from low-cost convertible bonds in 2024-2025 to high-cost preferred shares at 10-12.5%. This suggests that scaled acquisitions are becoming less sustainable.

The Real Focus for January 2026

Despite the challenges to cycle theory, January 2026 may still become a key node—just with a different driving force.

First, at the policy level. The US cryptocurrency market structure-related bill will be reviewed on January 15th, which could serve as an important catalyst for Bitcoin. It’s less about the cycle pattern and more about policy expectations driving the market.

Second, institutional movements. Over the past two days, BlackRock has withdrawn 7,146 BTC (worth $668.38 million) from Coinbase, a large withdrawal often indicating institutional outlooks. Matrixport expects a stronger influx of Bitcoin ETF funds in 2026, which could significantly boost prices.

Third, technical support. BTC is currently at $91,010, with mining difficulty recently adjusted downward by 1.20% to 146.47T, providing miners with some breathing room and potentially easing supply pressure.

Conclusion: The Cycle Continues, But It’s No Longer the Same

The four-year cycle theory of Bitcoin has not completely failed, but its driving forces have fundamentally changed. The coincidence of dates and timing suggests some structural pattern still plays a role; however, the deepening of institutional participation, policy environment changes, and increased market maturity are weakening the purely cyclical constraints.

January 2026 is likely to become a critical node, but this significance is more driven by policy review, institutional actions, and market expectations rather than traditional cycle theory. Investors should not blindly rely on the four-year cycle but focus on the progress of legislation, institutional movements, and real-time market structure changes. The cycle is still there, but it has evolved into a more complex, policy- and institution-influenced new cycle.
