A significant majority of Bitcoin’s supply, 81%, has remained inactive for at least six months, indicating a strong tendency for holders to retain their assets, according to data reported by River Financial. This trend of supply dormancy is occurring alongside a roughly 50% price increase from Bitcoin’s June lows, yet trading volumes have decreased by 30% year-to-date, and ETF inflows have been running below average.
Broader Context
Source materials place the factual news in this context: River Financial’s September 23 newsletter.
Holder Behavior Shifts
River’s data reveals a market where long-term holders are increasingly consolidating their positions. Since 2020, these holders have added over 3 million BTC. Concurrently, the movement of older coins has slowed to a trickle, with only approximately 300,000 BTC changing hands in the first half of 2026. This suggests a high degree of conviction among established holders.
The behavior of individual and retail investors also points to a sentiment shift. After selling a net 140,000 BTC in the first half of 2026, these participants began accumulating again in the third quarter, adding over 107,000 BTC. This transition from distribution to accumulation is a notable development in current market dynamics.
Accumulation Trends and Liquidity Implications
Further analysis highlights ‘dolphin’ wallets, defined as those holding between 100 and 1,000 BTC, as significant accumulators. Since mid-July, these wallets have acquired more than 113,000 BTC, indicating a targeted acquisition strategy.
The substantial dormancy of Bitcoin’s supply has implications for market liquidity. With approximately 19.7 million Bitcoin in circulation, the estimated ‘active’ float—coins realistically available for trading—is around 3.7 million BTC. The high percentage of inactive supply suggests that the pool of readily available coins for sale on exchanges is limited, potentially impacting market liquidity.
River Financial’s Position
River Financial’s own operational data, detailed in its September 23 newsletter, shows reserves of approximately 33,737 BTC against liabilities of around 33,499 BTC, with the company maintaining 100% Bitcoin reserves. This internal practice aligns with the broader market trend of holding and securing Bitcoin.
While the data indicates strong holder conviction and a shift in retail sentiment, the precise reasons for the increased supply dormancy and the exact duration of the inactivity period for the 81% of supply remain areas for further observation. The definitions of ‘long-term holders’ and ‘older coins’ also contribute to the nuances of interpreting these trends.
