Bitcoin’s long-standing four-year halving cycle is facing its biggest test yet, as BTC closes 2025 in the red—an outcome never seen in a post-halving year before.
Bitcoin Halving Cycle Explained
Bitcoin halvings occur roughly every four years, reducing miner rewards by half and slowing the issuance of new BTC. Historically, this programmed supply shock has driven a predictable market rhythm: accumulation after the halving, a powerful bull run into new highs, followed by a sharp correction and an extended bear market.
After the 2012 halving, Bitcoin surged to end the following year at a new all-time high. The same pattern repeated after the 2016 halving and again following the 2020 halving, reinforcing confidence in the so-called four-year cycle. Traders, analysts, and long-term holders came to rely on this framework to forecast Bitcoin price action.
However, 2025 may have disrupted that narrative for good.
Bitcoin Ends Post-Halving Year Lower
Despite the most recent halving taking place in April 2024, Bitcoin has ended 2025 lower than it began. According to CoinGecko data, BTC is trading more than 30% below its all-time high of $126,080, set on Oct. 6.
This marks the first time Bitcoin has declined in the year following a halving—an unprecedented break from historical behavior. At the time of writing, Bitcoin is trading near $87,624, reflecting prolonged weakness rather than the explosive post-halving rally investors had anticipated.
For many market observers, this development signals a potential structural shift in how Bitcoin trades.
Analysts Declare Four-Year Cycle Dead
Several analysts have argued for months that Bitcoin’s four-year cycle was losing relevance, and the red close in 2025 has strengthened that view.
Vivek Sen, founder of Bitcoin public relations firm Bitgrow Lab, stated in an X post that Bitcoin ending the year down confirms the cycle is now “officially dead.” He pointed to changing market dynamics and reduced reliance on speculative retail flows as key drivers behind the breakdown.
Investor Armando Pantoja echoed similar sentiments, emphasizing that today’s crypto market looks nothing like it did in 2016 or 2020.
“The market has new players,” Pantoja said. “ETFs, institutions, and corporate balance sheets don’t trade like hype-driven retail. Bitcoin trades macro now—BTC reacts to liquidity, interest rates, regulation, and geopolitics, not a perfect halving calendar.”
Institutions Reshape Bitcoin Price Dynamics
The launch of spot Bitcoin ETFs, growing corporate adoption, and increased institutional exposure have fundamentally altered Bitcoin’s market structure. Unlike retail-driven cycles of the past, large institutional players tend to allocate capital strategically, rebalance portfolios methodically, and hedge exposure rather than chase momentum.
Pantoja added that while the halving still matters in the long term, its impact is no longer automatic. With a significant portion of Bitcoin supply now locked in long-term custody, miners accessing alternative financing, and deeper liquidity across derivatives markets, price reactions to supply cuts have become more muted.
This shift suggests Bitcoin is increasingly behaving like a macro asset rather than a speculative commodity.
Crypto Leaders Split On Cycle Theory
While many executives believe the four-year cycle is fading, consensus across the crypto industry is far from unanimous.
Throughout 2025, figures such as ARK Invest CEO Cathie Wood, BitMEX co-founder Arthur Hayes, and Bitwise executives Matt Hougan and Hunter Horsley have publicly stated that Bitcoin’s historical cycle should no longer be treated as a reliable roadmap.
However, others argue that the cycle remains intact—just evolving.
Markus Thielen, head of research at 10x Research, said during a December episode of The Wolf of All Streets podcast that Bitcoin cycles still exist, but they are no longer dictated purely by programmed supply reductions. Instead, broader liquidity conditions, central bank policy, and macroeconomic stress now play a greater role.
According to this view, Bitcoin’s cycle hasn’t disappeared—it has simply merged with global financial cycles.
What Comes After The Cycle?
If the four-year cycle is truly broken, investors may need to rethink how they analyze Bitcoin markets. Strategies based purely on halving timelines could give way to frameworks centered on monetary policy, institutional flows, and on-chain supply dynamics.
At the same time, Bitcoin’s long-term fundamentals—fixed supply, decentralized security, and global accessibility—remain unchanged. While the post-halving playbook may no longer guarantee explosive gains, Bitcoin’s role as a macro hedge and digital store of value continues to strengthen.
Whether 2025 marks the final nail in the four-year cycle or just a transitional phase, one thing is clear: Bitcoin’s market maturity is reshaping how price discovery works in the crypto era.
