Wu Blockchain reports, according to Santiment data, BTC ETF outflows have exceeded $4 billion since May 7. Historical trends show that when large amounts of funds flow out of BTC ETFs in a short period, it often reflects peak levels of fear, frustration, or risk-averse sentiment among retail and institutional investors. Santiment believes that such massive withdrawals could indicate that a local bottom is approaching. https://(wublock123.com)/news/btc-etf-outflows-over-4b-since-may-7-61910
