For years, Bitcoin investors have debated whether the market truly follows a predictable four-year cycle driven by halvings. While some argue that institutional adoption and exchange-traded funds (ETFs) have disrupted the old rhythm, fresh analysis suggests the pattern remains intact. According to on-chain analytics firm Glassnode, Bitcoin’s recent price movements echo past cycles and may still be pointing toward a peak within the traditional four-year framework.

This revelation has reignited discussions across the crypto community. Is Bitcoin still bound by its historical cycles, or has a new era of institutional-driven price discovery begun?

Bitcoin’s Recent Price Behavior

After reaching a new all-time high of $124,128 in mid-August, Bitcoin has since cooled off, retracing by over 8% to trade around $114,000. While such pullbacks are common after euphoric highs, Glassnode emphasizes that the timing and depth of this correction resemble phases observed in prior market cycles.

Specifically, profit-taking by long-term holders — those who have held their coins for more than 155 days — has reached levels comparable to previous euphoric peaks. Historically, this behavior has marked moments late in the cycle when seasoned investors secure gains while newer participants chase momentum.

Weakening Demand Signals

Another key metric underscoring the maturity of this cycle is demand. Capital inflows into Bitcoin have begun to show signs of exhaustion. Spot Bitcoin ETFs, which saw record-breaking inflows earlier this year, have now posted outflows of nearly $1 billion over just four trading sessions.

This decline in appetite has coincided with increased speculative positioning in altcoins. Open interest in altcoin derivatives briefly reached an unprecedented $60 billion before correcting sharply, highlighting a shift of risk capital away from Bitcoin into higher-volatility bets.

Such trends often align with later-stage cycle behavior, when Bitcoin’s dominance dips as traders look for outsized returns in riskier assets.

Timing the Cycle Peak

If Bitcoin continues to follow its established four-year rhythm, a market peak may not be far away. Glassnode notes that in both the 2018 and 2022 cycles, peak highs occurred just two or three months beyond the current point when measured from the cycle’s bottom. This suggests that Bitcoin could reach its cycle high as early as October 2025.

Crypto analyst Rekt Capital supports this projection, arguing that if the market mirrors the 2020 cycle, the peak would likely occur roughly 550 days after the April 2024 halving — once again aligning with October.

These observations strengthen the case that, despite new variables such as ETFs and institutional treasuries, Bitcoin still responds to the underlying supply shock mechanics introduced by halvings.

The Argument Against the Four-Year Cycle

Not everyone agrees. Critics argue that the four-year cycle is losing relevance as Bitcoin matures and institutional adoption expands. Jason Williams, investor and author, recently highlighted that the top 100 treasury companies now hold close to 1 million BTC, a figure that fundamentally alters the dynamics of supply and demand.

Matt Hougan, Chief Investment Officer of Bitwise, has also dismissed the idea of a rigid four-year cycle. He believes the halving’s impact diminishes with each iteration and that broader macroeconomic factors, such as interest rate cycles, now play a larger role in shaping Bitcoin’s trajectory. Hougan even predicts that the next “up year” for Bitcoin could come in 2026, breaking away entirely from the halving-based timeline.

Institutional Influence: Disruptor or Reinforcer?

The rise of spot Bitcoin ETFs and public treasuries has undeniably changed the market landscape. ETFs provide regulated, accessible exposure for both retail and institutional investors, creating new waves of liquidity. Meanwhile, corporations integrating Bitcoin into their treasuries add long-term demand that differs from the speculative retail flows dominating earlier cycles.

However, these changes may not necessarily kill the four-year cycle. Instead, they could amplify it. By accelerating demand during bullish phases and intensifying profit-taking during corrections, institutional flows may reinforce cyclical patterns rather than erase them.

Historical Context: Why the Four-Year Cycle Matters

The four-year cycle theory is rooted in Bitcoin’s halving mechanism. Every four years, the block reward miners receive is cut in half, reducing the rate of new supply entering circulation. This event has historically triggered a supply shock, often followed by price surges as demand outpaces issuance.

In 2013, 2017, and 2021, Bitcoin recorded parabolic rallies that peaked roughly 12–18 months after halving events, followed by extended bear markets. While no cycle is identical, the structural impact of halvings has been difficult to ignore.

Today, the question is not whether halvings matter, but how much their influence is being diluted by the growing scale of institutional participation.

Possible Scenarios Ahead

Looking forward, several scenarios emerge:

• Cycle Intact: Bitcoin continues to follow its four-year rhythm, with a peak forming in late 2025 before entering another correction phase.
• Modified Cycle: Institutional flows alter the amplitude and timing of peaks, but the broad four-year framework remains relevant.
• Cycle Broken: Macroeconomic forces, ETF inflows, and treasury adoption create an entirely new pattern, making the halving less significant over time.

Regardless of which path unfolds, Bitcoin’s current behavior suggests that investors should prepare for heightened volatility in the months ahead.

History May Still Be Rhyming

While critics declare the four-year cycle dead, Bitcoin’s latest price action suggests otherwise. Profit-taking, weakening demand, and speculative flows into altcoins are all hallmarks of a late-stage cycle. If history repeats itself, a peak could arrive in just a matter of months.

Yet Bitcoin has matured. Institutional adoption, ETF flows, and macroeconomic forces mean that while the rhythm may remain, the song could sound different this time. Investors would do well to remain cautious, balancing optimism for potential new highs with the awareness that cycles — even if alive — always carry corrections in their wake.
