For the first time since 2012, Bitcoin hit a new all-time high *before* the halving. 2025 didn't look like a post-halving bull market — it looked like a front-run bear market. If everyone knows what's coming, everyone trades it earlier — and the classic October-2026 bottom around $40k might already be history. What this thesis implies for the months ahead.

The parallels between today and 1999 are striking — concentration, valuations, the CapEx wave, the circular deals between the big players. But in four places the picture is fundamentally different: profits, how the investments are funded, utilization, and the monetary backdrop. A sober comparison, without falling into either camp.

Every time Bitcoin corrects, the same reflex kicks in: "Relax, it's just the cycle." But where is this cycle written down? In which whitepaper, in which law of nature? Spoiler: nowhere. The 4-year cycle is pattern recognition built on three data points — and a self-fulfilling prophecy that makes exactly those traders exploitable who believe in it most. A critical dissection.

Gold has had three great bull waves since 1971. Bitcoin has run through four in just 17 years. The fifth is starting now — and it has no precedent.

In the last post we argued that adaptive normalization and institutional dampening are the future of cycle indicators. Then we built exactly one — and tested it honestly. The results forced us to reposition the indicator.

Everyone wants a reliable Bitcoin cycle indicator. Buy near the bottom, sell near the top. Simple concept. Surprisingly hard to build well. Here's what we learned trying to build one — and why the classic approaches are becoming less reliable with every cycle.
