Bitcoin (BTC) was changing hands near $77,600 on Thursday, roughly 38% below the record set in early October last year, when a prominent on-chain analyst asked whether the asset was leaving the four-year clock that has defined most of its price history.
The suggestion, framed as a question rather than a call, points to a longer macro rhythm borrowed from traditional finance and rests on the idea that Bitcoin’s programmed supply cuts no longer move the market the way they once did.
What Willy Woo Said
New Zealand-based on-chain analyst Willy Woo, whose verified account @willywoo describes his work as “numbers, mainly #Bitcoin related” and says he posts only on X, posted the question at 07:22 UTC on September 3, 2026.
The post opened, “BTC MOVES TO A 6-8 YEAR CYCLE?” He wrote that Bitcoin “has been locked into the gravity of a 4 year orbit” because of the “strong internal forces of its halvening,” which he called a “clockwork 4yr supply rate shock.”
Traditional finance (TradFi), he added, operates on a “6-8 year short term debt cycle.” With new supply “de minimis at 0.8% new supply per year, soon to be 0.4%,” Woo said the market “we may be witnessing right now its transition to a 6-8 year cycle.”
The term “halvening,” used interchangeably with “halving,” refers to a scheduled event in the Bitcoin protocol that cuts the reward paid to miners for adding a new block of transactions to the network. The cut happens every 210,000 blocks, roughly every four years, and reduces the pace at which new coins are created.
“De minimis” is a Latin legal and economic term meaning too small to matter, used here to argue that the current rate of new supply is now negligible relative to the total number of coins already in circulation.
Woo has more than 1.2M followers on X and is known in on-chain circles for models such as Network Value to Transactions (NVT) and various supply-shock oscillators, which attempt to translate blockchain activity into market-relevant signals.
The Issuance Math Behind the Claim
The numbers Woo cited match the schedule written into Bitcoin’s code. The fourth halving occurred at block 840,000 on April 19-20, 2024, cutting the block reward from 6.25 BTC to 3.125 BTC. At the target rate of roughly 144 blocks per day, the network now mints about 450 new BTC daily, or approximately 164,250 BTC per year.
Against a circulating supply near 20.08 million BTC in early September 2026, that pace works out to roughly 0.82% per year, which Woo rounded to 0.8%. The next halving is projected around April 2028 at block 1,050,000, when the reward will drop again to 1.5625 BTC and annual issuance will fall to roughly 0.4%, based on the same 210,000-block subsidy schedule.
Earlier halving eras were far more inflationary. Annual issuance ran near 8 to 10% after the 2012 halving, about 3.5 to 4% after 2016, and roughly 1.7 to 1.8% after 2020, based on the same 210,000-block schedule. The 2024 cut was the first time the rate of new supply fell below 1% of circulating coins, which is the mathematical basis for Woo’s argument that the “internal force” of the supply shock is now small.
How the Four-Year Pattern Formed
Bitcoin’s major peaks and troughs have historically clustered around its four completed halvings, on November 28, 2012, July 9, 2016, May 11, 2020, and April 19-20, 2024, with price highs following in late 2013, late 2017, late 2021, and October 2025.
Woo described the mechanism in an earlier era using the image of a bathtub. In an August 2020 explanation on the Investor’s Podcast Network, he said Bitcoin’s cycles worked because the halving acts like a timed shove, saying that if “you’re sitting in the bathtub and you kind of push the water at the right time,” the market builds a resonance that lasts more than a year.
That was the framing he defended for most of the last decade. The September 3 note argues the same push has become too weak to keep dominating once new supply is a fraction of 1%.
Woo’s Position Has Moved More Than Once
The comment is a shift in emphasis rather than a first-time claim about cycle change.
In March 2022, Woo floated what he called “The Last Cycle” thesis, saying that short bull-and-bear swings after 2019 suggested the clean four-year template was breaking as the market became more complex. That view was largely set aside as the 2024-2025 advance produced another post-halving all-time high.
On January 9, 2026, with Bitcoin near $91,000, Woo pushed back against a growing “cycles are dead” narrative. “Until orange climbs higher into 2026 and starts to weird non-cyclical stuff, this narrative on THE END OF 4 YEAR CYCLES is NOT supported by data,” he wrote, adding that flows into the BTC network were “declining according to past cycles.” In coverage of those remarks, Woo compared cycle skeptics to people who assume a heartbeat has stopped because it slows in sleep.
Two days later, on January 11, 2026, he said he was “bullish BTC late Jan through Feb but presently bearish for 2026,” citing weakening liquidity relative to price momentum since January 2025 and adding that a confirmed bear would require sustained negative flows, a lagging signal.
The Crypto Times reported in February on his three-phase bear-market framework, in which he told followers that Bitcoin’s bear trend was gaining strength and that volatility had spiked in a pattern that preceded major downturns in 2014-2015, 2018-2019 and 2022. About seven months later, the same analyst is asking whether the four-year clock itself is giving way, an explicit shift from the internal-shock argument he was still defending in January.
What “6-8 Year Short-Term Debt Cycle” Refers To
Woo did not point to a single academic paper in his post. In economic history, the closest standard reference is the Juglar cycle, identified in 1862 by French physician and statistician Clément Juglar as a fixed-investment and credit cycle in advanced economies. Standard textbook ranges place the Juglar cycle at roughly seven to eleven years, though Juglar himself wrote of prosperity phases lasting “six or seven years” before a shorter crisis and liquidation, according to later summaries of Juglar’s work.
Woo’s “6-8 year” phrasing sits at the short end of that literature rather than outside it. The comparison, however, is offered as an analogy in his post, not as a measured statistical correlation. Bitcoin’s entire trading history remains shorter than three full Juglar-length waves, which limits how strongly any such claim can be tested at this stage.
Other Analysts on Bitcoin’s Cycle
Woo is not alone in raising the question. Strategy Executive Chairman Michael Saylor, whose firm is the largest listed corporate holder of Bitcoin, has argued for months that the four-year cycle is over and that price is now driven by capital flows through spot exchange-traded funds (ETFs), corporate treasuries, sovereign funds and interbank collateral. “Price is now driven by capital flows,” Saylor wrote in an April 4, 2026 post.
Bitwise CIO Matt Hougan made a similar case in the firm’s 2026 outlook note, published in December 2025. “In our view, the forces that previously drove four-year cycles, the Bitcoin halving, interest rate cycles, and crypto’s leverage-fueled booms and busts, are significantly weaker than they’ve been in past cycles,” Hougan wrote, adding that Bitwise expected institutional capital to accelerate through 2026 and push Bitcoin to fresh highs, “relegating the four-year cycle to history’s dustbin.”
Fidelity Director of Global Macro Jurrien Timmer offered a different reading in commentary, arguing that the October 2025 peak of about $126,000 was the cycle top and that 2026 was likely to be an “off year” with support around $65,000 to $75,000, a view that keeps the four-year template intact.
Independent research from Blockware Solutions, went further in November 2025, calling the halving “noise” against the scale of ETF inflows and arguing that Bitcoin is now “a macro asset correlated with liquidity and business cycles.”
The Market Setting on the Day of the Post
Bitcoin’s all-time high of $126,080 was set on October 6, 2025, according to Coinbird’s tracker, which lists BTC at $77,882.04 in early September 2026, about 38.23% below that peak. Other widely cited prints put the October 6, 2025 intraday high near $126,273. Market capitalization stood near $1.56 trillion, with a circulating supply around 20.08 million BTC. Block reward remains 3.125 BTC, and the network is about 125,000 blocks into the current 210,000-block epoch that ends with the 2028 halving.
The 2024-2025 advance peaked 17 to 18 months after the April 2024 halving, inside the 12-to-18-month post-halving window that traders have used since 2013. The subsequent drawdown is the period Woo is now reading as possible evidence of a longer clock, rather than a standard mid-cycle dip or a classic four-year bear phase.
Domestically, The Crypto Times reported this week that Bitcoin was holding near $78,000 as South Korea’s Kimchi Premium returned to about 1%, and that August 2026 delivered a 24.95% gain, Bitcoin’s first positive August since 2021, a run that has now stalled going into the historically weak September stretch.
What Would Have to Be True for the Thesis to Hold
If issuance near 0.8%, and 0.4% after 2028, is genuinely too small to reset the older rhythm, then interest rates, credit growth, dollar liquidity, ETF flows and corporate treasury demand would need to carry more of the timing weight. That is a claim that can only be tested over several years, not several weeks.
Counterpoints exist inside Woo’s own 2026 record. In January, he said the four-year model remained the best fit until flows turned clearly non-cyclical. Bitcoin did print a new high in October 2025 after the 2024 halving, which is the pattern the four-year camp expected.
A single post-halving peak followed by a roughly 38% drawdown does not, on its own, prove the clock has lengthened to 6-8 years. It is also consistent with a late-cycle correction inside the older template, or with the multi-phase bear structure Woo himself outlined in February.
No dashboard in the September 3 post shows a completed six-to-eight-year Bitcoin wavelength, since the asset only began trading in meaningful size in 2010-2013. Sample size remains the binding constraint on either side of the argument.
How to Read the Statement
Woo presented the idea as a question and a possibility, using the phrase “we may be witnessing,” rather than as a completed measurement. The arithmetic on issuance is standard and checkable against the subsidy schedule and current circulating supply. The historical clustering of peaks and troughs around the four halvings is a matter of public dates and prices. The leap that remains contested is causal, namely that a smaller supply shock must now cede timing control to traditional-finance credit cycles.
For readers, the September 3 post is best treated as an update from an analyst who has both defended and questioned the four-year model at different points, now weighting protocol inflation low enough that he is willing to put a longer macro clock on the table. The next hard protocol event remains the 2028 halving. Between now and then, the evidence will be whether Bitcoin’s peaks and troughs line up more closely with credit and liquidity turning points than with the old four-year marks.
