Dolphin Cohort Accumulation Drives Bitcoin’s Late-Stage Cycle
CryptoQuant’s on-chain data indicates Bitcoin’s short-term momentum is cooling, yet long-term demand remains robust thanks to the 100–1,000 BTC “dolphin” cohort. These large holders now control 26% of circulating supply (5.16 million BTC) and have added over 681,000 BTC in 2025, while whales, fish and humpbacks reduced their balances. The dolphins’ annualized accumulation rate of 907,000 BTC surpasses its 365-day average of 730,000 BTC, underlining sustained institutional demand. However, their 30-day growth has dipped below the short-term average, aligning with Bitcoin’s recent pullback from $126,000. Analysts warn that continued strong dolphin accumulation is essential to maintain the bull trend and avoid a consolidation phase. Overall, on-chain patterns suggest the market is in late-stage cycle maturity rather than nearing a definitive end.
Bullish
Historically, increased accumulation by the 100–1,000 BTC “dolphin” cohort has coincided with significant price upswings, while slowdowns led to corrections. This cycle, dolphins have added over 681,000 BTC and maintain an annualized growth rate above the 365-day average, signaling strong structural demand. Although 30-day growth has dipped, the sustained high accumulation rate suggests bullish momentum persists. If dolphins continue to absorb supply, Bitcoin is likely to resume its uptrend and test new highs. This mirrors past cycles where institutional and large-holder buying preceded extended rallies, supporting a bullish outlook.
