Compared with history
Cooler than previous cycles

Bitcoin is later in the cycle by calendar timing, but cooler than previous cycles by price behaviour.

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.

What happened next

In previous cycles, what came after this point?

From the same day after the halving (863 days), here is how Bitcoin's price moved over the following months in each completed cycle. History is not a forecast, but it helps show how unusual or normal today's setup is.

If Bitcoin corrected like prior cycles…

Bitcoin has fallen sharply even in long-term bull structures. Here's where prior cyclical bear-market drawdowns from the cycle high ($124.82K) would imply — historical context, not a forecast.

Cycle divergence

What makes this cycle different?

The 2024 cycle is the first Bitcoin cycle with US spot ETF demand — a structural source of buying that did not exist in 2012, 2016 or 2020. That makes comparison with prior cycles useful, but not perfect. So far this cycle has been flatter and slower than the classic four-year rhythm.

What to watch next

Whether price begins to accelerate toward prior-cycle behaviour, plus ETFs have seen net inflows recently, and sentiment is greed. These are the signals that would show the cycle either converging with history or continuing to diverge.
