According to @rovercrc, ETH supply is being absorbed by ETFs faster than Bitcoin, signaling capital rotation into ETH (source: @rovercrc on X, Aug 20, 2025). For trading, monitor ETH/BTC relative strength and compare daily ETH ETF net creations versus BTC ETF flows to validate or fade the rotation narrative (source: @rovercrc on X, Aug 20, 2025). The post frames this as capital rotating toward ETH, implying near-term focus on ETH spot supply, price discovery, and spreads versus BTC among traders evaluating momentum and risk (source: @rovercrc on X, Aug 20, 2025).
