Odaily News Bitwise Chief Information Officer Matt Hougan said that the US spot Ethereum ETF may attract $15 billion worth of net inflows in the first 18 months after listing. Earlier news, on May 23, the US Securities and Exchange Commission approved the 19b-4 forms of 8 spot Ethereum ETFs issued by companies such as Bitwise, BlackRock and Fidelity. However, the issuer still needs to make its S-1 registration statement effective before it can start trading, which is expected to be approved in the next few weeks. (TheBlock)
