More than four out of every five Bitcoin in existence have remained inactive for at least six months, according to data from River Financial's September 23 newsletter. The 81% dormancy figure suggests a market where the majority of supply is held by investors showing little inclination to sell.
The timing of this data is notable. Bitcoin's price has risen approximately 50% from its June 2026 lows, yet trading volumes have declined 30% year-to-date and exchange-traded fund inflows have remained below average. This indicates that while fewer participants are actively trading, those who remain are holding their positions firmly.
Long-Term Holders Accumulate Supply
River's analysis reveals that long-term holders have added over 3 million BTC to their positions since 2020, effectively removing significant supply from the market. During the first half of 2026, approximately 300,000 BTC changed hands from these long-held holdings.
Retail Investors Shift to Accumulation
A significant change occurred among retail and individual Bitcoin holders. After selling a net 140,000 BTC during the first half of 2026, these participants reversed course and accumulated over 107,000 BTC during the third quarter.
The accumulation concentrated among mid-tier holders, known as "dolphin" wallets holding between 100 and 1,000 BTC. These wallets acquired more than 113,000 BTC since mid-July alone.
Implications for Market Liquidity
With Bitcoin's circulating supply at approximately 19.7 million coins, the 81% dormancy figure suggests roughly 3.7 million BTC remain in active circulation. This smaller "active" float represents the pool of coins that could realistically be sold on any given day.
