[K33 Research Director: Bitcoin ETF Fund Flows Heavily Depend on BlackRock] According to the latest data from K33 Research Director Vetle Lunde, Bitcoin ETFs have increased by $26.9 billion year-to-date. However, $28.1 billion of this growth comes from BlackRock's IBIT product. This means that excluding IBIT, the overall Bitcoin ETF fund flow is actually negative. It is worth noting that BlackRock will be absent from the upcoming altcoin ETF market wave. Analysts believe this situation provides an opportunity for other competitors to capture strong fund flows, but it may also limit the overall fund scale of the altcoin ETF market.
