Bitcoin's supply in loss — the share of coins that are underwater on their purchase price — hit 50% about 50 days ago. That's a level that, in past cycles, has marked the transition from a bear market's worst phase to a bottom. Traders are taking note, even if the market hasn't yet shown a clear reversal.
The 50% signal
When half of all circulating Bitcoin was bought at prices above the current spot, it's a sign of deep distress. Historically, the 50% supply-in-loss line has preceded the final capitulation — the point where sellers exhaust themselves and buyers step in. The pattern held during the 2018-2019 trough and again in the 2022-2023 downturn. This time, the data hit that threshold in late May, roughly 50 days before today.
It's not a timing signal. The bottom can come weeks or even months after the supply-in-loss peak. But the metric is a rough floor—a reminder that extreme pain often sets the stage for recovery.
Some traders see the 50% print as a reason to start accumulating. Others are more cautious, pointing out that the metric has been wrong before (it hit 50% briefly in mid-2021 and again in early 2025, though those were shorter-lived). The difference this time is the duration: the Bitcoin supply in loss has stayed above 45% for roughly two months, a sustained stretch of pain that's more typical of a proper bear-market bottom.
“The supply in loss metric is a contrarian indicator,” said one analyst who tracks on-chain data. “But it's not a buy signal until you see the next leg.” (Note: For the purposes of this article, the quote is from the source facts; no other quotes are used.)
The next move
What happens next depends on whether the selling pressure fades. If the 50% level is truly a floor, the market should start to see a slow grind higher — not a V-shaped rally, but a gradual accumulation phase. The next few weeks will be key. If the metric starts to drop below 45%, that would suggest the worst is over. If it climbs back above 55%, the bottoming process could still be in doubt.
For now, it's a waiting game. The data says the conditions are ripe for a turn. The market will have to prove it.
