Individual Bitcoin holders accumulated more than 107,000 BTC in the third quarter of 2026, reversing net sales of roughly 140,000 BTC across the first half, River Financial said. The firm recorded Bitcoin in the mid-$80,000s in its September 18 report and described the shift as the fastest retail accumulation pace in years. Wallets holding 100 to 1,000 BTC, which River calls dolphin wallets, added more than 113,000 BTC from mid-July, representing more than $9 billion at prevailing prices. The buying followed a first-half transfer of coins from individual holders to businesses and funds, including roughly 78,000 BTC sold by individuals in Q2 as businesses added about 115,000 BTC. Santiment separately estimated that wallets in the 100-1,000 BTC range added 113,950 BTC since July 15, lifting their balance to roughly 5.24 million BTC.
