The idea of a predictable four-year Bitcoin cycle has long been a cornerstone of crypto market analysis. Rooted in the blockchain’s built-in halving mechanism, this cycle has historically correlated with dramatic price swings, bull runs, and bear markets. But as Bitcoin matures and enters the mainstream—adopted by institutions, corporations, and even governments—many are questioning whether this once-reliable model still holds.
Recent sentiment reflects this uncertainty. A poll posted by the X account Bitcoin Archive asked whether the four-year Bitcoin cycle is over. Within ten hours, over 10,000 users voted, with 52% agreeing that the cycle may have run its course. While not definitive, this shift in perception signals a growing belief that market dynamics are evolving.
What Is the Four-Year Bitcoin Cycle?
At the heart of the four-year cycle is Bitcoin’s halving event—a programmed reduction in block rewards granted to miners. Every 210,000 blocks (approximately every four years), the reward for mining a new block is cut in half. This mechanism ensures Bitcoin’s supply remains finite, capped at 21 million coins.
The halving directly impacts supply dynamics:
- Miners receive fewer new bitcoins for the same computational effort.
- With reduced incoming supply, scarcity increases.
- If demand remains steady or grows, prices tend to rise.
Historically, this has created a rhythmic pattern:
- Post-halving accumulation phase: Prices stabilize or rise slowly as supply tightens.
- Bull market surge: 12–18 months after halving, prices often explode, reaching new all-time highs.
- Bear market correction: After peaking, the market cools, correcting from highs but usually settling above pre-halving levels.
This pattern played out clearly in past cycles:
- 2012 halving → 8,000%+ price increase within 12 months.
- 2016 halving → Bull run peaking in late 2017.
- 2020 halving → All-time high of nearly $69,000 in 2021.
Even the uneven growth in 2021—a “mere” 57% annual gain due to late-year corrections—still fits a broader upward trajectory.
Signs the Cycle Might Be Changing
Despite historical consistency, recent developments suggest the model may be losing its predictive power.
The 2024 halving introduced new behaviors. Unlike past cycles where miners sold aggressively to cover costs, many in 2024 chose to hold their mined Bitcoin. This "HODL" strategy reflects stronger conviction in long-term value appreciation and reduced reliance on immediate fiat conversion.
This behavioral shift alters supply pressure and could delay or dampen traditional price reactions. When miners aren’t flooding the market with coins, the usual post-halving scarcity narrative intensifies—but so does uncertainty about timing.
Moreover, macroeconomic factors now play a larger role:
- Regulatory clarity in major economies.
- Institutional adoption via Bitcoin ETFs.
- Geopolitical instability driving demand for decentralized assets.
These forces don’t align neatly with a four-year timetable. Instead, they introduce external variables that can accelerate or disrupt cyclical patterns.
Is the Four-Year Model Still Reliable?
In early 2025, Bitcoin surged to $108,786, surpassing its previous all-time high. On the surface, this aligns with the halving-driven bull market narrative. Yet, the rally was followed by volatility and consolidation, despite generally positive news—increased adoption, favorable regulations, and strong on-chain metrics.
This inconsistency has fueled debate. If the four-year cycle were intact, we’d expect a sustained bull run through 2025–2026, followed by a bear market. But what if we’re not in a traditional cycle at all?
Ryan Watkins, co-founder of Syncracy Capital, argues that the cycle is dead. In January 2025, he suggested abandoning terms like “altseason” and “four-year cycle,” citing the transformative impact of Bitcoin ETFs and institutional participation.
“Mostly agree with this, with the key difference that Bitcoin and everything else are likely on different timelines. Imo the asset class is beginning to bifurcate between Bitcoin + stablecoins, which are very much on the plateau of productivity, and everything else…”

Watkins envisions a new era where Bitcoin operates more like digital gold—less speculative, more stable, and increasingly integrated into traditional finance. In this world, price movements are driven less by halving countdowns and more by macro trends, adoption rates, and global monetary policy.
Core Keywords and Market Evolution
The debate over Bitcoin’s cyclical nature hinges on several key themes:
- Bitcoin halving
- Institutional adoption
- Market volatility
- ETF impact
- Supply scarcity
- Crypto cycles
- Price prediction
- Miner behavior
These keywords reflect both technical fundamentals and evolving investor psychology. While halving still reduces supply, its effect is now filtered through layers of institutional ownership, regulatory frameworks, and global economic conditions.
For example:
- ETFs allow pension funds and retail investors to gain exposure without holding private keys.
- Governments are exploring Bitcoin reserves (e.g., El Salvador).
- Stablecoins anchor liquidity in crypto markets, reducing friction.
All these factors contribute to a more mature ecosystem—one where simplistic cycle models may no longer suffice.
Frequently Asked Questions (FAQ)
Q: What causes the four-year Bitcoin cycle?
A: The cycle is primarily driven by the halving event, which cuts mining rewards in half every ~four years, reducing new supply and increasing scarcity.
Q: Did the 2024 halving follow historical patterns?
A: Partially. While prices reached new highs in 2025, miner behavior shifted—many held rather than sold—suggesting evolving market maturity.
Q: Are Bitcoin ETFs changing the market structure?
A: Yes. ETFs bring institutional capital, reduce volatility over time, and decouple price action from retail-driven cycles.
Q: Will there be a bear market in 2026?
A: If the four-year model holds, yes. But with increased adoption and macro influences, timing is less predictable.
Q: Can Bitcoin still be considered cyclical?
A: It may still exhibit cyclical traits, but these are likely becoming longer, less pronounced, and more influenced by external factors.
Q: What replaces the four-year cycle if it’s obsolete?
A: A more nuanced model combining supply shocks, institutional flows, regulatory developments, and macroeconomic trends.
The Road Ahead: A New Paradigm?
The four-year cycle was never a law—just a useful heuristic. As Bitcoin transitions from speculative asset to global reserve asset candidate, old models must evolve.
The 2025 price peak confirms that halving still matters. But the subsequent volatility suggests that new forces are at play. Whether we’re entering a post-cycle era or simply witnessing a more complex version of the same pattern remains to be seen.
What’s clear is that Bitcoin’s story is no longer just about code and cycles. It’s about adoption, regulation, macroeconomics, and human behavior at scale.
