Nasdaq has officially filed a 19b-4 form with the U.S. Securities and Exchange Commission (SEC) for the 21Shares Dogecoin ETF. This marks a significant step towards offering investors a regulated and accessible way to gain exposure to Dogecoin (DOGE), the popular meme cryptocurrency. The 19b-4 form is a crucial exchange rule change filing required by exchanges like Nasdaq when seeking to list new investment products, including ETFs. If approved by the SEC, the 21Shares DOGE ETF would trade on the Nasdaq, providing investors with a convenient avenue to invest in DOGE without directly holding the cryptocurrency. The SEC has been cautious regarding crypto ETFs, so the outcome of this application remains uncertain. However, this filing signals growing institutional interest in offering diverse cryptocurrency investment products to the broader market. This development may potentially pave the way for other meme coin-based ETFs in the future. ```
