According to Farside Investors, Bitcoin ETFs experienced a total net outflow of $85.7 million on May 6, 2025. Notably, Grayscale's GBTC saw significant outflows of $89.9 million, offsetting modest inflows of $36.7 million into BlackRock's IBIT. Other major funds, such as ARKB, EZBC, and HODL, also recorded net outflows, while funds like FBTC and BITB saw no net movement. Persistent net outflows from Bitcoin ETFs suggest ongoing profit-taking and cautious institutional sentiment, which could place short-term downward pressure on BTC prices and affect broader crypto market stability (Source: Farside Investors via Twitter).
