US Spot Bitcoin ETFs Post $296.18M Weekly Outflows by March 27 as Focus Shifts to Bitcoin L2

US spot Bitcoin ETFs recorded $296.18 million in net outflows for the week ending March 27, marking the first weekly net withdrawal since mid-February. The pullback came as Bitcoin briefly dipped to $65,000 last week before moving back above $67,000, while some market attention shifted toward Bitcoin Layer-2 projects such as Bitcoin Hyper (HYPER), which says its presale has raised more than $32.2 million.
