BlackRock ETF inflows have been rapid in the past few days, with Ethereum alone increasing its holdings by $420 million yesterday, and as a result, there is even bigger news today. Several companies operating ETFs have submitted amendment applications, hoping to support people to subscribe to ETFs with coins while holding BTC and ETH. In other words, in the future, you can not only buy ETFs with cash, but also hold BTC and ETH to subscribe to the corresponding ETFs. This has allowed many institutions and currency holders to have a place for professional institutions to be trusted, and large financial institutions like BlackRock have endorsed it, which also marks that BTC and ETH ETFs have begun to be treated as orthodox financial assets.
