According to @rovercrc, ETF flow data in the shared chart show ETH ETFs attracting stronger net inflows than BTC ETFs, indicating heightened institutional demand for ETH (source: @rovercrc, Twitter post dated Aug 20, 2025). The source states that blue is ETH and orange is BTC, and characterizes BTC as lagging, framing a rotation toward ETH that traders focused on relative performance may consider when allocating between the two assets (source: @rovercrc, Twitter post dated Aug 20, 2025). The trading thesis presented relies specifically on the comparison of net ETF flows between ETH and BTC in the chart, with the implication, per the source, that sustained ETH inflows could support continued relative strength versus BTC (source: @rovercrc, Twitter post dated Aug 20, 2025).
