According to Crypto Rover, current ETF data shows negative flows for Bitcoin while Ethereum ETFs are experiencing positive inflows. This indicates that institutional and retail investors are actively rotating capital from BTC into ETH, potentially impacting short-term price action and liquidity for both assets (source: Crypto Rover, Twitter, May 30, 2025). Traders should monitor ETH volume and inflow trends closely, as this shift in ETF flows may enhance ETH's volatility and trading opportunities while creating headwinds for Bitcoin in the near term.
