The analytics firm explained that this group plays a major role in shaping short-term structure, especially when retail activity moves in the opposite direction. During the recent recovery, whale inflows returned Bitcoin to a positive zone defined by shrinking supply pressure and renewed confidence among key stakeholders.However, the firm added that retail wallets continue to buy dips. While this activity supports price during short retracements, it prevents Bitcoin from entering the ideal structure where large holders accumulate while smaller wallets reduce exposure. Santiment stated that such a pattern could create a cleaner path for upward movement, similar to early September and early October.Even with retail participation remaining elevated, the shift in whale behavior has contributed to Bitcoin’s early-December stability. The reduced selling pressure has allowed the market to regain footing after a volatile end to November.$90K Becomes the Immediate Level to WatchMarket analyst Ted stated that Bitcoin retested the $88,000 level before producing a strong bounce.He noted that the next turning point sits at the $90,000 mark, which must be reclaimed for upward momentum to continue. A successful move above that threshold could lead toward $92,000, then $98,000, and possibly the broader supply region near $102,000.$BTC retested the $88,000 level and then had a bounceback.Bitcoin now needs to reclaim the $90,000 level for some upside.A failure to reclaim it will push BTC towards the $87,000-$88,000 level again. pic.twitter.com/oIgJLfPSy9— Ted (@TedPillows) December 6, 2025Ted added that failure to recover $90,000 may send Bitcoin back toward the $87,000–$88,000 zone. This area has acted as a defensive line where buyers repeatedly stepped in, signaling its importance. Another test of this region would shape the next phase of the current trend, especially as whales continue to build positions.With 47,584 BTC added to whale wallets and price compressing between defined technical levels, traders are watching for signs of a potential breakout.
