In my portfolio, I have ETF target assets like DOGE, XRP, LTC, and SOL, but there's something I need to share with everyone. On September 18, the first altcoin DOGE ETF in the U.S. was listed on CBOE, but its trading volume and holdings are relatively small, so it didn't send DOGE soaring. First, the listing of the DOGE ETF signals that more crypto ETFs will be listed in the future; second, ETFs not applied for by mainstream institutions or unable to list on Nasdaq have limited impact.
