The volume and flow data together paint a picture of a bitcoin ETF market that is losing near-term momentum while ether funds continue to attract a disproportionate share of new institutional interest. With bitcoin hovering near $64,000 and ether ETF net assets still a fraction of their bitcoin counterparts, the coming weeks will test whether the rotation is a temporary rebalancing or the start of a deeper structural shift. The key question now is whether bitcoin ETF volume can recover above the $9 billion weekly threshold that held through most of 2025, or whether the current lull signals a more lasting recalibration of institutional crypto allocations.
