Bitcoin's 4-Year Cycle Isn't Broken. It Just Lost the Halving Engine

Ask any crypto chartist whether Bitcoin's famous four-year cycle is broken and you'll get a long, heated argument. The data gives a cleaner answer than the argument does, and it starts with the one number neither side quotes: the cycle's clock didn't break at all.

Bitcoin topped on October 6, 2025, at about $126,000. That peak arrived roughly 1,050 days after the November 2022 low, essentially on top of the ~1,060-day average run of every prior bull market. The calendar that retail traders are told to watch did exactly what it was supposed to do. So when you hear "the cycle is broken," what's actually true is narrower and more consequential. The timing held. Two other things did not — and they're the ones that matter to your money.

The clock held

Here is the pattern people mean by "the four-year cycle." A halving every four years cuts the new bitcoin mined per block in half. Roughly a year later the price goes vertical into a euphoric top, then it crashes 75% to 85% into a multi-year bear market before the whole thing restarts. The tops tell the story: November 2013, December 2017, November 2021, and now October 2025.

The last peak was the odd one out in only one way worth noting — it came with no euphoria. At the moment of the top, Bitcoin's market value sat at only 2.3 times its realized value (the average price every coin last changed hands at). In 2013 that ratio hit 5.9, in 2017 it hit 4.7, in 2021 it hit 2.9. The signal that has caught every previous blow-off top never fired this time. The top happened on schedule, but it was the calmest top in the asset's seventeen years.

The size shrank

What actually declined is the size of the swings, not their timing. Peak-to-trough drawdowns have compressed with every cycle: 85% in 2013, 84% in 2017, 77% in 2021. This cycle, from the October high into mid-2026, Bitcoin fell about 51%, bottoming near $58,000 before recovering to roughly $77,000 today.

That is a real change, and it is the whole debate in one number. The people who say the cycle is broken point to the missing 77% washout and call it a new era. The people who say it's intact point to the drawdown that did happen and call it a normal, if gentler, bear. Both are reading the same tape and neither has the clean answer. The reason the washout shrank is more interesting than either story, because it says the old engine is gone.

The halving stopped being the engine

The traditional story is a supply shock: the halving cuts new supply, scarcity pushes price up. That mechanism is now economically trivial. The April 2024 halving cut Bitcoin's annual supply growth from about 1.7% to 0.85% — and roughly 94% of all bitcoin that will ever exist is already mined. Today miners add only about 450 bitcoin a day, roughly $35 million at current prices. Against a market that trades tens of billions a day, that is a rounding error.

The marginal buyer is no longer the retail trader reacting to a supply cut. It is the institution. The U.S. spot ETFs that launched in January 2024 now hold over $60 billion of bitcoin in BlackRock's fund alone, and that money moves on macro liquidity, not on the halving schedule. That is why Bitcoin fell with stocks during the 2022 rate-hike cycle, rallied as liquidity loosened into 2025, and now pivots on inflation and Federal Reserve policy. The halving used to be the catalyst for a four-year rhythm. The new catalyst is global money supply, and it doesn't run on a four-year clock.

Before you take comfort in that, note the two-sidedness. Institutional money raises the floor — it's why the drawdown was 51% instead of 77%. But it can also leave. Spot bitcoin ETFs logged their worst month on record in June 2026, and their flows have swung from months of outflows to a $1.3 billion March inflow and back again, tracking inflation prints and geopolitics more than any block reward.

What should change for you

The honest verdict is that "broken" is the wrong word. The cycle keeps its schedule; it has just lost its engine, so its size keeps shrinking. The tradeable consequence is blunt: stop planning around the halving. Fidelity, no crypto cheerleader, warns investors not to use the four-year cycle as a precise framework — tops and bottoms drift, and this top, on schedule as it was, arrived pre-euphoria with no reliable blow-off signal to sell into.

If the pattern holds, historical timing points to a bottom roughly 12 to 13 months after a top — placing the window in the last quarter of this year. Galaxy's analysts, using the higher cost basis institutions created, put the base case well above the old-rule 80% crash, around $40,000 to $46,000, with a shallower floor near $51,000 to $54,000 if long-term holders keep absorbing selling. Those are estimates built on a compressed pattern, not certainties, and a deeper washout remains possible if a panic pulls the average cost basis down with it.

The useful shift in thinking is this: Bitcoin no longer offers the clean, periodic, supply-driven trade the halving narrative promised. What it offers instead is a scarcer version of the same proposition — a fixed 21 million coins set against institutions that now allocate and redeem with the Fed. That makes the risk-reward driven less by a calendar and more by your view of liquidity. Position accordingly, and stop asking which year the cycle breaks. That framing is the dead weight.
