Bitcoin whales and sharks—defined as wallets holding between 10 and 10,000 BTC—added approximately 11,000 Bitcoin to their holdings over the past week. The accumulation occurred as Bitcoin traded at $64,392, below the critical $65,000 threshold.

This tier has historically tracked closely with Bitcoin's price trajectory. Their buying during a period of retail profit-taking signals a shift in market dynamics worth watching.

On-chain analysis from Santiment shows this buying behavior could drive upward momentum. The Crypto Fear & Greed Index sits at 25—Extreme Fear—a level that has historically preceded significant price rallies.

For a confirmed bullish move, Bitcoin must clear $65,000 and hold it. That break would validate the accumulation trend and open the door to targets in the upper $60,000 range and toward $70,000, contingent on strong spot demand and continued inflows into Bitcoin spot ETFs.

High-value transaction volume is the key indicator to track. If those transactions hold while Bitcoin trades above $70,000, it signals absorption of selling pressure, not distribution—meaning larger entities are buying available supply and pulling coins off exchanges, tightening the float.

If Bitcoin fails to clear $65,000 and high-value transactions dry up, this accumulation stalls. Sustained retail selling without institutional demand keeps prices range-bound.
