$BTC Gate News: On March 15, Santiment reported that key investors holding 10 to 10,000 Bitcoin are accumulating, currently controlling 68.17% of total supply, up from 68.07% seven days ago. Santiment believes the recent increase in Bitcoin whale accumulation represents a "positive reversal," and the platform is closely monitoring retail selling to confirm a potential market bottom. Additionally, Bitcoin is showing rare strength relative to the S&P 500 index, breaking typical correlations during the current geopolitical conflict. Data shows the S&P 500 declined approximately 2.2% over the past five weeks, while Bitcoin rose 2.4% and gold rose 3.7%.
