The U.S. Securities and Exchange Commission (SEC) has initiated a public comment period on Canary Capital's application for a Litecoin ETF, following the acknowledgment of the firm's filing under Form 19b-4. This move marks the first time an altcoin ETF has been recognized by the SEC, with Nasdaq set to list the ETF if approved. The public has 21 days to submit comments, and a decision from the SEC is expected within 240 days. The potential approval of the Litecoin ETF is seen as having the highest chance of success, with some market predictions suggesting an 87% likelihood of approval this year.
