The anatomy of a crypto cycle

The folk model goes like this. Halving, quiet accumulation, a slow rise, a retail mania, an eighty percent collapse, a long winter, repeat. It has described four cycles, which is both impressive and far too few observations to trust.

What is worth separating is the mechanics that recur for structural reasons from the patterns that are simply what happened.

The mechanics that genuinely recur

Leverage builds at the top and unwinds violently. This is not sentiment, it is plumbing. As price rises, traders borrow against holdings. A fall triggers liquidations, liquidations sell into a falling market, which triggers more. The cascade is a mechanical amplifier and it will happen in every cycle because the instruments exist. Funding rates and open interest measure it in advance.

Liquidity moves outward and returns inward. Money enters through bitcoin, rotates into ether, then into large alternative coins, then into small ones. On the way down it reverses, and the smallest assets fall furthest and recover least. Bitcoin dominance measures this rotation directly.

Leverage is concentrated in the least regulated places. Each cycle's largest failure has been at whichever venue was offering the most leverage with the least oversight. This has been true four times.

The pattern that is probably coincidence

The four-year rhythm is credited to the halving. It also coincides with a rough four-year rhythm in global liquidity and, less comfortably, with the US electoral cycle. With four observations, these cannot be told apart statistically.

The liquidity explanation has an advantage: it also explains why technology stocks, small caps and speculative credit moved in the same direction at the same times. A theory that explains bitcoin alone is less likely than one that explains everything that behaves like a risk asset.

What actually changed this cycle

The buyer base. ETF flows come from advisers and allocators who rebalance on a schedule and do not use leverage. That dampens the amplitude at both ends.

Regulation. Licensed venues in Europe and stablecoin rules in the United States removed the specific mechanisms behind the largest previous failures. Something else will fail; it will fail differently.

Derivatives depth. Regulated futures and options markets are deep enough that professional hedging happens onshore. That reduces the chance of a single offshore venue taking the market down with it.

The result is a cycle with lower realised volatility and a higher correlation with traditional risk assets. Those two things arrive together and you cannot have one without the other.

The indicators worth watching, and the ones that are not

Worth watching: funding rates and open interest, which measure leverage; stablecoin supply, which measures dry powder on the sidelines; ETF flows; bitcoin dominance; and the fear and greed index at its extremes, where it has some contrarian value and in the middle none at all.

Not worth watching: any model that fits a curve to four cycles and extrapolates it. Price targets derived from a logarithmic regression are drawing, not analysis. Stock-to-flow models in particular failed badly after 2021 and have not recovered their credibility.

What a cycle-aware investor actually does

The honest answer is boring: size the position so that an eighty percent drawdown is survivable, use a mechanical schedule rather than a judgement call about the top, and rebalance on a rule. Our savings plan simulator exists to show what that looks like across a range of outcomes rather than a single one.

What to watch

Watch whether the next drawdown is shallower than seventy percent, which would be the first hard evidence that the buyer base changed the asset. Watch correlation with equities in a risk-off week. And watch where the leverage has moved to, because it is always somewhere.
