Gate.io reported: The key stages for the approval of the Ethereum ETF include submitting a 19b-4 application and an S-1 registration form to obtain approval from the Securities and Exchange Commission (SEC) and list on the exchange. These forms outline rule changes and product details such as fund structure and investment strategies. Although they are important, approval does not guarantee the ETF will be available to the public. Delays or rejections may impact market sentiment and volatility. The approval from the SEC is crucial for Ethereum to become a mainstream investment.
