A bitcoin metric that has telegraphed every major bear-market bottom in the cryptocurrency's history just triggered again. More than half of all circulating bitcoin is now sitting on unrealized losses, according to on-chain data, as the price tests levels that have marked the floor in previous cycles.
What the metric says
The indicator — a ratio that compares bitcoin's market price to its realized value — has flipped negative for the first time this year. In every prior cycle, that signal marked the moment when selling pressure exhausted and accumulation began. The last time it appeared was during the 2022-2023 downturn, just before prices turned higher. This isn't just some newfangled oscillator; it's a reading that has correctly called the bottom on every single occasion since the metric first existed.
Half the supply underwater
Right now, more than 50% of all bitcoin in circulation was acquired at prices above the current spot level. That means a majority of holders are staring at red on their cost basis — a psychological weight that tends to either freeze sellers or shake out the last weak hands. Historically, when the share of coins in profit drops below 50% for an extended stretch, the market is nearing the end of its capitulation phase. The question is not whether it will flip, but how long it stews here.
Testing the historical floor
The price is currently probing a zone that has acted as a support floor in every prior bear market. It's a band that has caught every drop since 2015, though obviously past performance is no guarantee. What's different this time is the macroeconomic backdrop: interest rates remain elevated, and liquidity has been tight across risk assets. The bitcoin-specific on-chain story, however, remains historically consistent.
What traders are watching
The next few weeks will show whether this metric holds its perfect record. If the price holds above that support level and the unrealized loss percentage starts to tick down, the bottom could already be in. If it breaks, the market will be in uncharted territory — no metric has a 100% hit rate forever. For now, the data is flashing the same signal it always has at the darkest point of the cycle.
