Bitcoin's 32% loss a year past its peak is less than half what each earlier cycle lost

Had this bear market matched the mildest of its predecessors, a 77% fall from the high ^[9], bitcoin would have bottomed near $29,000. Matching the harshest, 85%, would have meant about $19,000 ^[19]. Instead the price has risen about 45% from its June low ^[21].

Tim Sun, senior researcher at HashKey Group, puts as much weight on timing as on depth. "The most notable changes are the significantly shortened duration of the drawdown and the reduced time spent at the bottom," he told CoinDesk ^[11]. He tied it to the buyer base, saying buyers this cycle "increasingly stem from outside the crypto market, including ETFs, asset management giants, family offices, and even corporations" ^[2]. As a result, he said, "the market did not trigger the persistent negative feedback loops seen in the past" ^[4].

Griffin Ardern, co-founder of Primal Fund and a portfolio manager on its volatility desk, said ETF allocation money "rebalances to target weights" and "buys weakness by construction" ^[5]. He said leverage was cleared out right at the top and never properly came back ^[12]. "Hence nine months to grind out a 53% decline, rather than a few months of cascading liquidations taking it down 80%," Ardern said ^[13].

"As bitcoin evolves and more participants come to market, the realized volatility of the asset will decrease. This means shallower drawdowns and lower peaks," said Jeff Anderson, head of U.S. at market-making firm STS Digital ^[15]. Ardern's rule points the same way. Money that rebalances to a target weight buys bitcoin when it falls below that weight and, by the same rule, sells when it rises above it. In a sizing model the two effects pull against each other. A smaller expected loss supports a bigger position; a smaller expected peak supports a smaller one. Which wins depends on which tail compresses more, and the record has one post-ETF cycle to set against three earlier ones ^[7].

This could go differently in at least two ways. Leverage that Ardern says never properly came back can rebuild during a rally, so a later sell-off would again force liquidations. Allocators can also withdraw money instead of rebalancing toward their weights. CoinDesk describes this downturn as a macro-led reversal of the institutional ETF inflows that drove the 2023-25 rally ^[1]. Sun said it was largely caused by capital outflows after changes in the macroeconomic environment and in asset allocation ^[3]. I think the evidence supports a narrower range in both directions for this cycle, with ETF allocators as the likeliest reason. It does not establish a floor. CoinDesk's summary of the analysts' warnings adds that a shallow correction does not rule out sharper downside ahead ^[17].
