Did Bitcoin bottom in 2026? The 4-year cycle says not yet

Bitcoin's four-year cycle low in 2026—a daily close of $58,525 on June 30 in the CoinMetrics data series—arrived 267 days after the October 6, 2025 peak; in the three previous cycles, the bottom fell between 364 and 406 days after the top. It is also the first bear market low that did not push the MVRV (the ratio of market capitalization to realized capitalization, which values each coin at the price of its last on-chain movement) below 1: it marked 1.103 compared to 0.564 in 2015, 0.690 in 2018, and 0.754 in 2022. Based on these two metrics, this article presents a thesis with a resolution date: Bitcoin will close below $58,525 before the end of November 16, 2026, and the first of those closes will fall within the peak-to-trough calendar window, from October 5 to November 16.

Thesis status as of Sep-14-2026: No closes below $58,525 since June 30; latest CoinMetrics close, $78,279 (day 343 post-peak).

What does the Bitcoin bottom thesis claim and what would make it false?

1. Primary Claim. Between September 16 and November 16, 2026, inclusive, Bitcoin will record at least one daily close below $58,525 in the CoinMetrics PriceUSD series. If November 16, 2026, ends without such a close, the claim is false: the June 30 low will have been the cycle bottom, and the peak-to-trough calendar followed by the 2015, 2018, and 2022 cycles will have been broken in the 2024-2026 cycle.
2. Secondary Claim, evaluated separately. The first daily Bitcoin close below $58,525 in the CoinMetrics PriceUSD series will fall within the window of October 5 to November 16, 2026—days 364 to 406 counted from the October 6, 2025 peak. A close prior to October 5 would confirm the primary claim but fail the secondary one.

The Binance intraday low ($57,800.19 on July 1, 2026) does not count. The intermediate checkpoint is October 19, 2026, day 912 after the April 20, 2024 halving, equivalent to the latest bottom in the series when counted from the halving (2022); October 5 to 19 is the only period where both methods of cycle counting overlap. The final assessment will be published on November 16, 2026, with a single data point: the date and price of the first close below $58,525, or its absence. A "strong version" is noted outside the main thesis: a close below $37,447 (a -70% drop from the peak) within the window.

The window is measured from the peak because it tracks the duration of the bear market phase; using November 29, 2013 ($1,128.73) as that cycle's peak instead of December 4 would extend the window to November 21, 2026, though the resolution remains set for November 16.

How many days passed between the peak and the bottom in previous Bitcoin cycles?

The three previous bottoms arrived 406, 364, and 366 days after their respective peaks in the CoinMetrics daily series; the current cycle's low arrived at 267 days.

The peak of this cycle arrived on schedule: 534 days after the halving, falling between the 525 days of 2017 and the 546 days of 2021. The June 30, 2026 low did not arrive on schedule. It occurred 97 days earlier than the earliest bottom in the series (364 days, in 2018) and 139 days earlier than the latest (406 days, in 2015). Applied to the October 6, 2025 peak, these two extremes define the window from October 5 to November 16, 2026. Using CoinMetrics daily closes, two of the three bottoms fell in U.S. midterm election years (Dec-15-2018 and Nov-9-2022) and one in the following year (Jan-14-2015).

The table uses the maximum and minimum daily PriceUSD values for each phase, calendar days between dates, and the halvings at blocks 210,000, 420,000, 630,000, and 840,000. The closing peak for the current cycle was $124,824.45; the Binance intraday high on that same day, October 6, 2025, was $126,199.63, and using intraday prices, the drawdown is 54.2% instead of 53.1%. The 2022 bottom allows for another date: November 21, 2022, closed at $15,778.02, just $19.73 above the November 9 close, on day 378, also within the interval. The mechanics synchronizing the cycle with the halving are detailed in the analysis of the four-year cycle mechanics and its projection to 2029.

How much further did previous Bitcoin cycles have to fall on day 343 post-peak?

Day 343 after the current cycle's peak was September 14, 2026, with a close of $78,279; on that same day of their respective cycles, the three previous ones still had between 16.3% and 58.4% left to fall until their final bottom.

One of the three paths ends below $58,525: the 2015 path, at $32,534. The 2018 path stops at $65,503 and the 2022 path at $63,074. Each path multiplies the September 14, 2026 close by the ratio between the final bottom and the price on day 343 of its cycle, sharing the same limitation as the calendar and MVRV: only three observations. The count is sensitive to the chosen day: on day 342 (Sep-13-2026), two out of three paths were below the threshold, because on November 24, 2018, that cycle closed 11.3% lower than the previous day. Reaching the threshold requires a -25.2% drop from the September 14 close, or -23.0% from the Binance price of $76,035.65 on September 15, 2026, at 19:53 UTC.

The closest precedent due to its late bounce is 2014. Measured against the then-current low, from October 5, 2014 (day 305, $322.83) to November 12 (day 343, $422.59), Bitcoin rose 30.9%, before falling 58.4% to the January 14, 2015 bottom. Using the same metric with a peak occurring after day 300, the largest bounces prior to the bottom were 14.6% in 2018 and 18.7% in 2022.

Why doesn't the June 2026 MVRV look like a cycle bottom?

The MVRV was below 1 at the 2015, 2018, and 2022 bottoms, after spending 34, 27, and 115 days in that zone, respectively; the June 30, 2026 low remained at 1.103 without dropping below 1 on any day.

Realized capitalization adds each Bitcoin at the price of its last movement; divided by supply, it gives an average on-chain acquisition cost, and an MVRV below 1 means trading below that cost. The day count runs from peak to bottom for each cycle based on the CapMVRVCur series (own calculation). The MVRV stood at 1.471 on September 14, 2026, and the implicit realized price (price divided by MVRV, own calculation) was $53,070 on June 30 and $53,219 on September 14. A bottom with an MVRV below 1 would require a close below approximately $53,200, which is 9.1% below the $58,525 threshold. The regularity of the MVRV suggests the bottom has not yet arrived, but it does not specify when.

The limitation is the sample size—three observations—and a cycle that has already deviated from the range in terms of depth: a -53.1% drop compared to drawdowns between 76.7% and 84.5%. A minimum MVRV above 1 could be part of this same regime change.

At what prices did Strategy sell Bitcoin in 2026 and where is its average cost?

Strategy (formerly MicroStrategy, the public company with the most Bitcoin on its balance sheet) sold Bitcoin four times between June 29 and August 9, 2026, totaling 6,916 BTC, at prices between $59,256 and $64,262—all below its average cost of $75,412.

According to its 8-K filed on September 14, 2026, Strategy held 845,050 BTC at an average cost of $75,412, with the CoinMetrics close on September 14 sitting 3.8% above that cost. The sales are supported by a program approved on June 29, 2026, allowing it to sell Bitcoin to, among other purposes, fund its USD Reserve—a dollar reserve for preferred dividends and interest, which totaled $5.10 billion on September 13; it also maintains $1.30 billion in USD Cash for general use. STRC is its variable-dividend preferred stock. No 8-K sets a specific price at which it will sell. The context for these decisions is found in Strategy's trilemma and its Bitcoin sale to support STRC.

What levels and dates are being monitored for Bitcoin until November 16, 2026?

On September 14, 2026, the hashprice (a miner's daily revenue per unit of computing power, in dollars per petahash per day) was $38.61, compared to $27.48 on June 30, and the cumulative net flow of spot Bitcoin ETFs was $4.16 billion above its June 30 level.

Miners. Calculated with the 450 BTC daily subsidy and excluding fees, the hashprice would return to the June 30 level with Bitcoin at $58,781 following the difficulty adjustment estimated for September 19 (+5.50% in the Sep-15 extraction; own calculation). This price replicates the revenue pressure of June and does not include production costs or the break-even point for any specific miner. MARA Holdings, a U.S.-listed Bitcoin miner, states in its Q2 2026 10-Q filing that it sells its produced Bitcoin continuously and may sell reserves; it held 35,577 BTC as of June 30. The June difficulty cut is discussed in the analysis of the 10% difficulty cut and the June 2026 hashprice.

ETFs, stablecoins, and Mt. Gox. From the October 6, 2025 peak to June 30, 2026, U.S. spot Bitcoin ETFs saw net outflows of $10.11 billion, according to flow aggregator SoSoValue. From July 1 to September 14, 2026, $4.16 billion flowed in—41.2% of what had left—with $160.0 million on September 14 following four negative sessions from the 8th to the 11th (-$462.7 million). The USD stablecoin supply measured by DefiLlama totaled $310.30 billion on September 15, up 0.23% from June 30. The Mt. Gox balance is equivalent to approximately $2.7 billion at $78,279 per Bitcoin (own calculation); on June 2, 2026, its addresses moved 10,422.65 BTC, mostly to a new address, without reaching any exchange.

The power law floor countdown published on July 30, 2026, projected October 25 as the date when price and the model floor would cross if Bitcoin remained at $63,999. The model floor surpassed $58,525 on July 18, 2026, and stood at $61,696 on September 14, with Bitcoin 26.9% above it. With the price unchanged, that cross will no longer occur on October 25: it shifts to June 12, 2027 (own calculation using the exponent implicit in that piece's milestones). By November 16, 2026, the model floor will be $65,266, meaning a close below $58,525 would pierce it by more than 10%.

What data points suggest that June 30, 2026, was indeed the cycle bottom?

The bounce from the June low reached 38.8% by September 3, 2026 ($81,243, day 332), and the cycle drawdown stopped at 53.1%: these are the two data points that best explain why the primary claim might prove false.

The bounce is the most significant counterargument. If the price remains above $58,525 on November 16, this is the interpretation that prevails.

Depth is the second. From 2015 to 2018, the drawdown cushioned by 0.7 points; from 2018 to 2022, it cushioned by 7.1 points; in this cycle, the jump is 23.6 points. A regime change of this magnitude, coinciding with the first cycle featuring spot ETFs and corporate treasuries, may also alter the duration of the bear market phase. This reading is plausible, though no data in the series proves it; it is what would remain if the thesis is falsified. The hypothesis of a monetary regime change is further developed in Warsh's fiscal dominance thesis and its effect on the Bitcoin cycle.

The halving clock is the rival interpretation to the peak-to-trough calendar. Counted from the April 20, 2024 halving, previous bottoms fell between days 777 and 912—June 6 to October 19, 2026—and June 30, at day 801, is already within that range.

What happens if Bitcoin does not close below $58,525 before November 16, 2026?

If November 16, 2026, ends without a CoinMetrics daily close below $58,525, both the primary and secondary claims will be false, and the cycle table will include a fourth row showing 267 days between peak and bottom, outside the 364 to 406-day range of 2015, 2018, and 2022.

If October 19, 2026, arrives without a close below the threshold, the secondary claim will have 28 days remaining, from October 20 to November 16.
