Onchain Pulse #2: Is the Bitcoin 4-Year Cycle Dead? What the Data Says

Something happened in 2025 that had never happened before in Bitcoin’s history. The year following a halving — historically Bitcoin’s strongest year, the window when supply shocks collide with growing demand and prices go parabolic — finished in the red. Bitcoin closed 2025 down approximately 6% from its January open, making it the first negative post-halving year on record.

The previous post-halving years returned 5,500% in 2013, 290% in 2017, and 420% in 2021. And then: -6% in 2025.

This one data point has ignited the biggest structural debate in the Bitcoin investing community right now. Is the four-year cycle — the framework that has guided Bitcoin investors since 2013 — officially dead? Or is it simply evolving into something more complex? And crucially: what does onchain data actually say about where we are in the cycle right now?

That’s what this week’s Onchain Pulse is built around.

Current Metric Snapshot — March 2, 2026

Before the cycle debate, the weekly data:

• Bitcoin price: ~$67,000–$68,000
• Realized price: ~$55,019 (market trading ~22% above aggregate cost basis)
• MVRV Z-Score: 0.5–0.8 (green accumulation zone, unchanged from last week)
• STH-SOPR: Recovered above 1.0 on Feb 16, hovering near breakeven
• Exchange reserves: Watching for net outflow resumption — still elevated
• Bitcoin ETF flows: Choppy — $560M single-day inflow (Feb 2) followed by $133M outflow (Feb 18)
• LTH supply: Near all-time highs — long-term holders not distributing

The headline metrics haven’t shifted dramatically from last week. But the context around them has become more important to understand — which is why this week we’re going deeper on the cycle question that everyone is asking.

Metric of the Week: LTH Supply (Long-Term Holder Supply)

Long-term holders are defined as addresses that have held Bitcoin for more than 155 days. They are the conviction cohort — the wallets that have held through crashes, through bear markets, through every panic and every mania. Their behavior is the most structurally meaningful signal in Bitcoin’s onchain data.

Right now, LTH supply is sitting near all-time highs. That means the most experienced, most patient holders of Bitcoin are not selling. They’re accumulating, or at minimum, they’re HODLing through the current correction.

This matters enormously for the cycle debate. At every previous Bitcoin cycle top — 2013, 2017, 2021 — LTH supply declined significantly in the months leading up to the peak. Long-term holders distributed into strength, selling to the waves of new retail buyers arriving late to the rally. That distribution pattern is what created the conditions for the subsequent crash: supply flooding the market as demand from new buyers eventually exhausted itself.

That distribution pattern is not present right now. LTH supply near all-time highs with Bitcoin down 46.7% from its October 2025 peak of $126,296 is the opposite of a cycle-top distribution signal. It looks far more like mid-cycle accumulation — experienced holders adding to positions or simply refusing to sell — than the beginning of a multi-year bear market.

This is one of the most important onchain facts in the current market, and it receives far less attention than price charts.

The Cycle Debate: Both Sides Have Real Arguments

Let’s steelman both positions honestly, because the data supports nuance rather than a clean verdict.

The case that the cycle is dead or fundamentally broken:

The mathematics of the halving have changed fundamentally. The April 2024 halving reduced Bitcoin’s daily new supply from 900 BTC to 450 BTC — roughly $40 million per day at current prices. That sounds significant until you compare it to U.S. spot Bitcoin ETFs, which routinely see daily flows of $500 million or more. On peak days in 2025, ETF inflows topped $1 billion — equivalent to absorbing 25 days of mining supply in 24 hours. The marginal price driver is no longer the halving’s supply reduction. It’s institutional flow.

Bitcoin’s correlation with the S&P 500 and NASDAQ reached 0.90 during periods of geopolitical stress in 2025. That kind of correlation to traditional risk assets doesn’t exist in an asset class driven by its own internal supply dynamics — it exists in a macro asset that moves with global liquidity conditions and Federal Reserve policy. The 2025 cycle also saw lower retail participation than any previous cycle, with institutional investors now estimated to represent over 60% of Bitcoin trading volume. When institutions dominate, the halving supply shock matters less because institutional mandates respond to portfolio allocation decisions, not mining economics.

The case that the cycle lives — and is simply maturing:

Fidelity’s director of global macro, Jurrien Timmer, has noted that Bitcoin’s October 2025 peak of ~$126,000 arrived roughly 145 weeks into the rally from the 2022 bottom — which “fits pretty well with what one might expect” from prior cycles. The cycle didn’t break. It just peaked earlier than the calendar suggested it should, because institutional and ETF-driven demand pulled forward the demand that historically arrived from retail buyers in the post-halving year.

The 2025 post-halving year was negative in annual return terms, but Bitcoin still peaked in Q4 2025 — consistent with the historical rhythm of post-halving peaks arriving 12–18 months after the halving event. The magnitude differed (a 100% rally rather than 300%+), but the timing structure held. The halving cycle isn’t dead — it’s being compressed by a larger, more liquid market that requires proportionally larger capital flows to produce the same percentage moves.

Onchain data offers a partial tie-breaker. The MVRV Z-Score at 0.5–0.8 is nowhere near the readings that have historically preceded multi-year bear markets. The 2018 bear market began with MVRV Z-Score above 7. The current reading at 0.5–0.8 is consistent with mid-cycle consolidation — a painful correction within a broader uptrend — rather than the beginning of a sustained 2–3 year collapse.

Macro Context: The Variable That Now Drives Everything

Whether you believe the cycle is dead or alive, both sides agree on one thing: Federal Reserve policy now matters more to Bitcoin’s price than mining economics. This is new, and it’s important.

The Fed began cutting rates in late 2025 and halted quantitative tightening. The resumption of liquidity expansion has historically been one of the strongest macro tailwinds for risk assets. Bitcoin, now deeply integrated into institutional portfolios via ETFs, responds to liquidity conditions alongside equities. More global liquidity means more capital available to flow into risk-on assets — including Bitcoin.

The path of the Fed in 2026 is therefore one of the most important variables for the Bitcoin market, independent of any onchain cycle analysis. A sustained easing cycle would provide the macro oxygen that Bitcoin needs to mount a significant recovery. A policy reversal — rate hikes returning due to inflation resurgence — would create a sustained headwind regardless of what onchain accumulation metrics show.

Watch the dot plot. Watch M2 money supply. These weren’t variables that mattered to Bitcoin investors in 2016 or 2020. They very much matter now.

What to Watch This Week

Three specific developments to monitor in the coming days.

First, LTH supply direction. If long-term holder supply begins declining meaningfully from current near-record levels, that changes the structural picture significantly. It would suggest that the most patient money is beginning to exit — historically a sign that the recovery thesis is weakening. Continued stability or growth in LTH supply reinforces the accumulation narrative.

Second, exchange reserve trend. As flagged in Onchain Pulse #1, the +13,000 BTC net inflow to exchanges in the week of Feb 11–17 remains the primary near-term caution signal. Until this reverses to sustained net outflows, upside momentum will be capped by available sell-side supply. Track this weekly on CryptoQuant’s exchange reserve chart.

Third, STH-SOPR sustainability above 1.0. The February 16th crossover back above 1.0 was the signal we flagged last week. The question now is whether it holds. A sustained STH-SOPR above 1.0 for 2–3 weeks confirms that the capitulation selling has genuinely cleared. A quick reversal back below would suggest the recovery is fragile and another leg down is possible. Monitor via CryptoQuant’s STH-SOPR chart.

The Bottom Line

The honest answer to “is the Bitcoin four-year cycle dead?” is: probably not dead, but meaningfully different. The timing structure of the cycle appears intact — the 2025 peak arrived roughly where historical patterns suggested it would. The magnitude and character of the cycle has changed — driven more by institutional flows and macro conditions than by mining supply shocks and retail speculation.

For onchain analysis purposes, the most important takeaway is this: the current data does not look like the beginning of a prolonged multi-year bear market. LTH supply near all-time highs, MVRV Z-Score in the green zone, and SOPR recovering from capitulation levels are the signatures of a correction within a broader structure — not a structural breakdown. Whether that structure is the traditional four-year cycle or something evolving beyond it, the data says the same thing: this looks more like accumulation than collapse.
