Bitcoin ETF Flows on June 1?

Regulatory news—such as SEC guidance on Bitcoin products or spot ETF approvals—can shift capital flows significantly. Macroeconomic events, geopolitical developments, and major corporate or institutional Bitcoin purchases or sales also drive sentiment. Additionally, market volatility, options expiration cycles, and quarter-end rebalancing by large funds can create temporary or sustained flow shifts heading into June 1.
