Why This Matters

A record share of Bitcoin supply sitting dormant could reduce the amount readily available for trading, making market liquidity more sensitive to large buy or sell flows. The figure does not prove those coins are permanently lost, however; any coordinated movement of long-idle holdings could instead create meaningful supply-side volatility.

Bitcoin (BTC) that has not moved in over a decade has reached 3.56 million BTC, representing approximately 17.7% of the circulating supply. The figure was reported on August 16 by Darkfost, an analyst at on-chain analytics firm CryptoQuant, in a post on X (formerly Twitter), marking an all-time high. At roughly $63,700 per BTC, approximately $226.8 billion (about ¥36.2 trillion) worth of Bitcoin has effectively vanished from the market.

According to Darkfost, more than 14,000 BTC entered the "unmoved for 10+ years" category in just the last 30 days. "While old BTC occasionally moves, the overall lost supply continues to grow," Darkfost noted, describing it as "a dynamic that naturally reduces circulating supply."

Bitcoin's total issued supply surpassed 20.07 million BTC as of August 2026, meaning approximately 95.6% of the 21 million BTC maximum supply has already been mined. As the theoretical cap approaches, the data highlights that the amount actually moving in the market is even smaller than headline figures suggest.

Dormant BTC Suddenly Moved in July 2025

Not all BTC that has been idle for over a decade is permanently lost. In July 2025, 80,000 BTC from address clusters dormant since 2011 suddenly moved, catching the market by surprise. Darkfost referenced this event while maintaining that the overall trend of growing dormant supply continues.

A decade of silence does not necessarily prove loss of private keys. Inheritance scenarios or ultra-long-term holding strategies could also explain the inactivity, and the 3.56 million BTC figure remains an estimate. Nevertheless, the fact that such a large quantity has remained unmoved for an extended period suggests Bitcoin's effective circulating supply may be smaller than the statistical figures indicate.

Supply Scarcity Could Support Medium- to Long-Term Price Floors

The scale of 3.56 million BTC becomes particularly striking when compared with the Japanese market. Metaplanet, known for its ongoing Bitcoin accumulation strategy, holds 43,000 BTC—dormant BTC is roughly 83 times that amount.

While supply scarcity is viewed by some as a potential medium- to long-term price support factor, there is also the risk that if dormant BTC were to move en masse in the future, it could create significant selling pressure. The 80,000 BTC movement in July 2025 serves as one example, and market participants are closely monitoring on-chain data trends.

Bitcoin mining output crossed the 20 million mark in March 2026. With less than 1 million BTC remaining to be mined, the combination of declining new supply and growing dormant supply suggests that effective circulating supply may be tighter than official statistics indicate.
