The launch of the Dogecoin ETF by REX Financial and Osprey Funds on September 18 marks a significant milestone for US investors, allowing them to trade the meme-based cryptocurrency through traditional brokerage accounts. The ETF recorded a first-day trading volume of nearly $18 million, indicating strong demand. Despite this success, analysts express skepticism about the inclusion of memecoins in capital markets, arguing that they lack fundamental value and could mislead investors regarding their legitimacy. The SEC's recent approval of a new ruleset for crypto ETFs is expected to facilitate the introduction of more such funds, although the rationale for memecoins remains contentious. Critics warn that the speculative nature of memecoins could lead to significant financial losses for uninformed investors, raising concerns about the role of regulators in protecting the public.
