Bitcoin Supply in Loss Exceeds 50%: A Historic Bottom Formation Signal
A key on-chain metric has just crossed an important psychological threshold: more than half of the total Bitcoin (BTC) supply is currently in a state of unrealized loss (“supply in loss”). Historically, this crossing of the 50% threshold has preceded bottom formation phases, offering an interesting analytical framework for investors. At the time of writing, Bitcoin is trading around $63,115, down from its recent highs above $65,000.
What Is the “Supply in Loss”?
The “supply in loss” is an on-chain indicator that measures the number of bitcoins whose acquisition price (the price at which each UTXO was last moved) is higher than the current market price. In other words, it represents the proportion of the total BTC supply that is currently in an unrealized loss position.
This indicator is calculated by comparing the price of each UTXO (Unspent Transaction Output) to the current BTC price. If the market price is below the acquisition price, the UTXO is considered “in loss.” The aggregation of all these UTXOs yields a percentage of the total supply in loss.
Unlike sentiment indicators such as the Crypto Fear & Greed Index (currently at 27, in “Extreme Fear” territory), supply in loss relies on objective blockchain data — there is no survey or subjectivity involved. It is a direct reflection of holder behavior.
The 50% Signal: A Historically Significant Threshold
The move above 50% supply in loss is a relatively rare event in Bitcoin’s history. Each time this threshold was crossed in the past, it marked — with a lag of several weeks — a bottom zone, that is, a price region where BTC subsequently reversed its downtrend to begin a new bullish cycle.
What makes this signal particularly interesting is its track record: it does not predict an immediate bottom, but rather a bottom formation window spanning approximately 50 days. Historical cycles show that the price can still fall or stagnate for several weeks after the 50% threshold is crossed, before finding a durable floor.
This ~50-day window can be explained by the very mechanics of a bear market: holders at a loss must either capitulate (sell at a loss, which further lowers the price and clears excess supply) or hold their positions while waiting for a reversal. The capitulation process can take several weeks, especially in an uncertain macroeconomic environment.
The Current Context: A Complex Macro Landscape
Several factors contribute to the current pressure on Bitcoin:
- U.S. Monetary Policy: after more moderate inflation data (June CPI and PPI) that pushed BTC above $65,000, the market remains uncertain about the pace of Fed rate cuts. Recent comments from Fed officials suggest a cautious approach, which limits risk appetite.
- Bitcoin ETF Outflows: although ETFs recorded a buying streak of $368 million over three days, the overall flow remains volatile. The recent break above $65,000 was not followed by an acceleration of inflows, suggesting caution among institutional investors.
- Geopolitical Context: tensions between the United States and Iran continue to fuel uncertainty, with implications for energy markets and, by extension, overall risk sentiment.
- Ether Underperformance: ETH continues to underperform relative to BTC, with the unwinding of “chip trades” and a 10% drop in HYPE. This imbalance between the two largest cryptocurrencies suggests a market that favors the relative safety of Bitcoin in times of uncertainty.
What Do Historical Cycles Say?
To contextualize the current signal, let’s look at previous crossings of the 50% supply in loss threshold:
- 2014-2015: during the bear market that followed the Mt. Gox collapse, supply in loss remained above 50% for several months. The final bottom was reached in January 2015 at around $200, with a window of ~60 days between the threshold crossing and the floor.
- 2018-2019: the bear market following the $20,000 peak saw supply in loss exceed 50% in November 2018. The bottom at $3,200 was reached in December 2018, roughly 40 days later.
- March 2020: the COVID-19 crash pushed supply in loss above 50% abruptly. The bottom was reached within a few days ($3,850) — a special case because the shock was exogenous and the recovery was rapid.
