Essentially, only Yu San Jia has the possibility of large funds, and among Yu San Jia, Grayscale is a seller. In fact, based on the fund data of BTC and ETH, only users of BlackRock and Fidelity have made large-scale purchases, while the rest, whether they are advertisements or not, have a pitifully small amount of funds even if they pass. This principle is similar to DeFi, where everyone is willing to exist on a larger platform that is more secure and guaranteed, rather than some newly emerged small platforms.
