Bloomberg ETF analyst Eric Balchunas said that BlackRock's position in Bitcoin holdings is strengthening, and the question now is "when" it will surpass MicroStrategy, not "if". Analysis found that the total trading volume of BlackRock and Fidelity's two spot Bitcoin ETFs has exceeded $3.1 billion so far, most of which are inflows. In contrast, although the trading volumes of Grayscale's GBTC and ProShares' BITO have reached $4.65 billion and $3.26 billion respectively, accounting for more than 60% of the total trading volume, most are outflows likely due to investors choosing to sell after recouping losses from the past year.
