According to Crypto Rover, BlackRock has just reported its largest-ever Bitcoin ETF outflow, marking the first withdrawal after 52 consecutive days of inflows (source: Crypto Rover on Twitter, May 31, 2025). This significant outflow signals a potential shift in institutional sentiment and could introduce increased short-term volatility in the cryptocurrency market. Traders should closely monitor Bitcoin ETF flows, as large movements from major asset managers like BlackRock often precede price swings and liquidity changes in BTC spot and derivative markets.
