Cycle comparison

Every halving cycle, lined up from day zero.

All four cycles drawn on the same axis, aligned to halving day. See how today's cycle compares with the prior three at the same number of days after the halving.

Later-running · cooler cycle

Bitcoin is currently tracking below every previous cycle at the same point after the halving.

Historically, two of the three previous cycles had already reached their major peak by this point after the halving. The current cycle is behaving differently — flatter and slower, and potentially more structurally supported by ETF demand. This does not guarantee future upside, but it does suggest the current cycle is not following the classic four-year rhythm cleanly.

Cycle timing

When could the current cycle top and bottom?

Highs and lows from the three completed cycles, measured in days after the halving. They cluster — and the cards below project those windows onto the current cycle (cycle 5), which began at the April 2024 halving.

Where we are

Across the three completed cycles, the bull-market high landed 371–546 days after the halving, and the bear-market low 777–924 days after. Cycle 5's highest price so far came at day 532 — inside that historical peak window. Today is day 772 — right as that low window opens. If this cycle echoes the last three, the comparable low would land between roughly Jun 2026 and Oct 2026. This is the rhythm of only three cycles, and the ETF era may break it — context, not a forecast.

Diminishing returns

Each cycle's peak gain has been smaller than the last — 92×, 30×, 8.4× for the 2012, 2016, 2020 cycles. If that pattern continues, this cycle would deliver a far smaller multiple than past cycles rather than a repeat of early returns. History, not a forecast.

ETF-era divergence

The 2024 cycle is the first with US spot Bitcoin ETFs — a source of demand that did not exist in 2012, 2016 or 2020. If that demand stays structural, it could change the shape of the cycle relative to history. The flatter, cooler profile so far (above) is the chief evidence — though it's still early, and this is not a guarantee.
