The Bitcoin cycle didn’t break—traders just forgot what drives it. This was originally prepared as a Strategy report, but given its importance to active allocators, we are sharing it here. Why this report matters Crypto is crowded with misleading narratives and surface-level analysis that lack statistical rigor yet spread quickly whenever they hint at overnight riches. Retail traders often get caught in this cycle, driven more by emotion than evidence. But beneath the noise, the market can be assessed quantitatively; it just requires proper data access, disciplined modeling, and independent thinking rather than hype. Conceptual frameworks such as stock-to-flow and global liquidity overlays became deeply fashionable. Yet, none of them signaled selling anywhere near the last cycle peak—in fact, most doubled down as Bitcoin was already breaking lower. Now, the same voices insist the four-year cycle has “evolved” into a five-year one, rather than acknowledging their models failed at the exact moment they were needed. Below, we outline the only driver that truly explains the four-year rhythm, and examine whether it remains intact or has finally broken. Main argument In previous reports, we highlighted that the widely cited stock-to-flow model had already broken down during the last cycle (see the May 10, 2024, report). Instead of the near-constant 10x appreciation it projected as supply declined, Bitcoin delivered diminishing cycle returns of 560x → 108x → 21x → 4x, roughly one-fifth of the prior cycle each time. This framework is why a $70,000 peak for 2024 was a realistic expectation, a level that did, in fact, cap price action from March until early November 2024, just before the post-election breakout. There is no mathematical law dictating that returns must compress by exactly one-fifth each cycle, but the stock-to-flow model clearly failed to serve as the infallible guide many believed it to be. ...
