According to ChainCatcher, BlackRock and Grayscale are competing for the top spot in the Bitcoin ETF rankings. In the past two weeks, Grayscale's lead has shrunk by half, and the gap between the two has now narrowed to $1.5 billion. BlackRock's current asset management scale is $17.2 billion. Previously, Eric Balchunas, senior ETF analyst at Bloomberg, predicted that IBIT would surpass GBTC by the end of April. It seems unlikely that this prediction will prove to be correct, but it may not be far from the target.
