Bitcoin’s Post-Halving Historical Pattern: Will It Repeat This Time?

Bitcoin's post-halving historical pattern — the four-year cycle — remains intact, but the "halving rule" that drives the cycle is losing its influence significantly. After the October 2025 all-time high of approximately $126,000, Bitcoin pulled back by about 50% without breaking below the global cost basis of $54,000, consistent with a cycle that is still whole but with narrowing amplitude. Will history fully repeat itself? Probably not — volatility will shrink, bottoms will be higher, but the conclusion that the decline is not over yet is justifiable at this point.

1. First, define what the "historical pattern" includes — before judging "repetition"

The "historical pattern" isn't a vague statement; it includes three quantifiable dimensions:

• Dimension 1: Drawdown magnitude. The bear market drawdowns after the first three halvings were −85% (2013–2015), −84% (2017–2018), and −77% (2021–2022), each narrowing.

• Dimension 2: Timing pattern. Historically, after each top, the bottom occurred roughly 12–13 months later. As of July 2026, only about 9 months have passed since the October 2025 top — the time window hasn't been reached yet.

• Dimension 3: Bottom anchor pattern. In all three previous bear markets, the lows were clearly below two anchor points — the global cost basis (Realized Price) and the 200-week moving average. On average, it was about −33% below the cost basis and around −14% below the four-year moving average.

It's crucial to understand the historical values of these three dimensions, rather than simply knowing "it dropped a lot before." A common mistake is comparing only the "50% drop" figure against history. Galaxy Research explicitly notes that the depth of the current pullback needs to be assessed simultaneously against the time window and anchor points — relying solely on the drawdown percentage can lead to misjudgment.

2. Check current data — compare against the three dimensions to see what "aligns" and what "diverges"

Filling current key data into the three-dimension framework (source: Galaxy Research / 21Shares Mid-Year Report, 2026-07-08):

In summary, currently "not enough time, price not low enough, not enough fear." The distance from historical bottom conditions remains. The global cost basis (~$54,000) is the average purchase price for all Bitcoin holders. When price falls below this figure, it means everyone is on average underwater — a necessary condition for bottoms historically. Galaxy Research analysts clearly state that the "base case bottom" for the current pullback is expected in the $40,000–$46,000 range, likely in Q4 2026, not that a bottom is confirmed just because of a 50% drop.

3. Understand "what's different" — why this time may not fully repeat

Institutions broadly believe the post-halving historical pattern will "continue but deform" for three reasons:

• ETFs changed the demand structure. After spot ETFs were approved in January 2024, Bitcoin shifted from "retail speculation-led" to "institutional allocation-led." Global crypto ETPs collectively hold around 1.25 million BTC, and institutional buying power far exceeds daily miner output (only 450 BTC). The supply reduction from halving is almost negligible in the face of ETF flows.

• Volatility continues to narrow. Peak MVRV (market value to realized value) fell from 5.91 in 2013 to 2.29 in 2025; trough MVRV rose from 0.56 in 2015 to 0.75 in 2022. Each euphoria is calmer, each trough is shallower.

• Macro factors outweigh halving factors. Bitcoin's correlation with global M2 money supply has reached 0.87, while its correlation with halving events is only 0.42. The direct trigger for the November 2025 sell-off was cooling expectations for Fed rate cuts, not post-halving supply changes.

In a nutshell, institutional money has replaced retail sentiment, and the impact of macro liquidity has surpassed the supply impact of mining halvings, so cycle amplitude is contracting, but direction remains. The 21Shares mid-year report plainly states: although the cycle shape remains similar, "market drivers have completely shifted from the supply side to the demand side."

4. Determine the current position — is the decline over or is there more room?

Based on the signals from the three dimensions, a framework for judging the current cycle stage can be formed:

• Number of bottom signals triggered: Out of 13 historical bottom signals tracked by Galaxy Research, only 4 have been triggered so far (fear sentiment, first breach of 200-week moving average, miner hash ribbon reversal), while historically all 13 signals eventually fire at bottoms.

• Cost basis breach: In every historical bear market bottom, price clearly fell below the cost basis; this cycle, price has never broken below the cost basis ($54,000) to date.

• Time window: Historical bottoms appeared 12–13 months after the top; only about 9 months have passed. Galaxy Research projects a bottom window in Q4 2026.

Based on this, we are in a "mid-cycle" phase, not a "cycle bottom," and the conditions for historical repetition have not yet been met. Caution: JPMorgan has launched structured notes tied to Bitcoin's four-year cycle, with product design logic fully aligned with the rhythm of "2026 decline, 2028 new bull." But this is not an "institutional confirmation" signal; rather, JPMorgan is selling products — they can hedge to earn spreads, not necessarily believing in this forecast.

Finally, it is recommended to add the following three data points to your regular watchlist:

① The distance between Bitcoin price and the $54,000 cost basis; ② The number of bottom signals tracked by Galaxy Research (key focus: whether MVRV falls below 0.75); ③ The number of months since the October 2025 peak. These three metrics respectively correspond to the dimensions of "price depth, fear level, and time window." When all three conditions are met simultaneously (price near $40K, MVRV < 0.75, time approaching 12 months), then reassess whether "the bottom has arrived" — until then, the signal from historical patterns is: it's not over yet.
