Bitcoin ETFs shed $450M in three days as September selling pressure mounts

U.S. spot Bitcoin ETFs reportedly experienced approximately $450 million in net outflows over three days, signaling renewed selling pressure as September began. The withdrawals indicate weakening near-term institutional demand and add to historically cautious seasonal sentiment around Bitcoin. If sustained, the outflows could weigh on prices and increase volatility, although the data reflects short-term flows rather than a definitive change in Bitcoin’s longer-term trend.
