K33 Research: Bitcoin Bear-Market Bottoms Came 13-101 Days After 50% Supply in Loss

K33 Research says past Bitcoin bear-market bottoms arrived 13 to 101 days after the share of Bitcoin supply held at a loss crossed the 50% mark, a historical timing signal that places the current cycle inside, rather than beyond, that window at a reported 42 days.

• What to know: K33 Research is framing the 50% supply-in-loss level as a reference point for bear-market bottoms.
• Prior bottoms reportedly followed that threshold by 13 to 101 days.
• The current count sits at roughly 42 days, still within the historical band.

What K33 Research Is Signaling About Bitcoin’s Cycle

The analysis comes from K33 Research, which examined what happens after half of all Bitcoin in circulation moves into an unrealized loss. For related coverage, see Shiba Inu Exchange Outflow Rises as Market Volatility Returns.

“Supply in loss” refers to the portion of coins whose last on-chain movement happened at a price higher than the current market price. When that figure crosses 50%, more than half of the circulating supply is underwater relative to its acquisition cost.

The firm frames the 50% threshold as a historical marker tied to prior bear-market lows, not a guarantee. It is a pattern drawn from past cycles, and past behavior does not lock in a future outcome.

How the 13-101 Day Historical Window Shapes the Setup

According to the K33 framework, past Bitcoin bear-market bottoms occurred between 13 days at the minimum and 101 days at the maximum after supply in loss passed 50%. That spread is the core of the signal.

The breadth of the range is itself the point: prior cycle outcomes were not uniform, so the metric functions as a probabilistic band rather than a precise date. Timing windows like this can compress in one cycle and stretch in another.

The reported current reading of 42 days sits between the 13-day floor and the 101-day ceiling, which places the market inside the historical window rather than past it. Bitcoin’s underperformance has been visible in relative terms, with the S&P 500 outpacing Bitcoin on a risk-adjusted basis over the recent stretch.

What the 42-Day Reading Could Mean for Bitcoin Next

Because 42 days falls between the 13- and 101-day boundaries, the signal can be described as still active in historical terms, as reporting on the K33 timing analysis has noted. That is a possible bottoming window, not a confirmed reversal.

Traders and investors track capitulation-style metrics like supply in loss because they attempt to gauge how much of the market is sitting on paper losses, a condition that has historically clustered near cycle lows. The metric describes positioning, not a trigger.

The brief provides no additional confirmation signals, so any conclusion stays conditional. The picture remains mixed in the background, with steady spot Bitcoin ETF inflows on one side and corporate treasuries such as Grant Cardone’s firm continuing to add BTC on the other.

For watchers of cycle lows, the K33 reading is constructive on its own terms, but incomplete without a confirmed reversal in price. The signal keeps the focus squarely on Bitcoin’s own supply dynamics rather than any broader altcoin move.
