K33 Research Says Bitcoin Bear-Market Bottoms Followed 50% Supply-in-Loss

K33 Research says past Bitcoin bear-market bottoms have followed the share of Bitcoin supply held in loss crossing above 50%, an on-chain threshold the firm frames as a marker of broad market stress. With roughly half of Bitcoin now sitting below its acquisition price, the historical pattern has drawn fresh attention from traders watching for capitulation signals.

What K33 Research Means by Supply in Loss Crossing 50%

Supply in loss is an on-chain measure of how much circulating Bitcoin was last moved at a price higher than the current market price. When the metric crosses 50%, more than half of all coins are, on paper, held at a loss. For related coverage, see T. Rowe Price launches crypto ETF with XRP, Bitcoin and Ethereum.

K33 Research has described the current backdrop in a note titled "Half of Bitcoin is underwater," which frames the 50% reading as a point where selling pressure and unrealized losses become widespread across the holder base.

A high supply-in-loss reading is often read as a sign of capitulation, because holders who bought at higher prices face the choice of selling into weakness or waiting out the drawdown. For related coverage, see Binance Futures to Launch SPCXUSD1 USD-M Perpetual Contract on July 20, 2026.

TLDR KEYPOINTS

• K33 Research says prior Bitcoin bear-market bottoms followed supply in loss rising above 50%.
• Supply in loss tracks the share of Bitcoin held below its acquisition price.
• The firm frames the 50% threshold as a marker of broad market stress, not a standalone buy signal.

Why Earlier Bitcoin Bear Markets Make This Threshold Notable

The core of K33's thesis, as reflected in the headline, is historical: the firm says past bear-market bottoms came after supply in loss moved above 50%.

Historical pattern versus interpretation

Repeatable thresholds attract market attention because they give traders a concrete line to watch instead of a vague sense of "cheap." K33 addresses the current cycle context in its H1 2026 round-up, which situates the underwater-supply reading within the broader market backdrop.

The historical pattern and its interpretation are distinct. That prior bottoms followed the crossing does not mean the crossing itself caused them, and K33 presents the metric as context for capitulation rather than a mechanical trigger.

What Traders and Analysts May Watch After the 50% Signal

One metric does not confirm a bottom by itself. Supply in loss describes where holders stand relative to cost basis, but it does not settle questions of timing, depth, or whether selling has actually exhausted.

On-chain analysts have echoed the underwater-supply framing, with a CryptoQuant Quicktake examining how loss-holding cohorts behave during drawdowns. Confirmation typically requires more than a single reading, since thresholds can flash before a low or produce false signals that reverse.

Limitations and risk framing

For readers, the practical takeaway is a monitoring one, not investment advice. A 50% supply-in-loss reading raises the stakes of the current drawdown, but it sits alongside institutional flows worth tracking, including moves such as T. Rowe Price's crypto ETF launch and Morgan Stanley's E*Trade Bitcoin rollout, that shape demand independent of any single on-chain metric.
