According to @santimentfeed, wallets holding 10–10K BTC (whales and sharks) have net accumulated 47,584 BTC so far in December after cutting holdings by 113,070 BTC from October 12 to November 30 (source: Santiment on X, Dec 5, 2025). Santiment reports BTC has moved into a blue-zone regime where both key stakeholders and retail are accumulating, a setup that historically leads to more up than down and aligns with observed positive momentum in early December (source: Santiment on X, Dec 5, 2025). Santiment notes retail dip-buying is capping upside and states that the most reliable bullish backdrop in their framework is the green-zone condition where whales accumulate while small wallets distribute, citing rallies seen in September and early October (source: Santiment on X, Dec 5, 2025). For traders, Santiment emphasizes monitoring net flows of 10–10K BTC wallets versus small wallets to gauge a potential shift from blue to the more favorable green zone for trend continuation (source: Santiment on X, Dec 5, 2025).
