US spot Bitcoin ETFs recorded $227 million in net outflows last week, extending a negative flow streak to six consecutive weeks. The 30-day average outflow is $212.2 million per day, and today's flow z-score sits at +0.55 against that mean, indicating the pace of institutional selling is not intensifying. An analyst cited in the article says the selling wave is exhausting itself, which historically has preceded stabilization rather than acceleration of outflows.
