The U.S. Securities and Exchange Commission (SEC) is currently reviewing the regulatory approach for 'new ETFs', receiving numerous submissions from cryptocurrency-related companies. Major U.S. asset manager Grayscale and Swiss cryptocurrency ETF operator 21Shares have expressed their unique demands, including a revision of the filing review process. Grayscale proposed the introduction of a voluntary procedure allowing for the submission of draft filings in private before listing, arguing that this could reduce the motivation to submit imitative and duplicative applications.
