21Shares has submitted its sixth amended S-1 filing to the U.S. Securities and Exchange Commission (SEC) for a proposed spot Dogecoin ETF. The ETF, which would trade under the ticker TDOG on Nasdaq, is set to have a 0.5% management fee with Coinbase serving as the custodian. At launch, 21Shares plans to purchase $1.5 million worth of Dogecoin. Despite the lackluster performance of existing Dogecoin ETFs, 21Shares continues to advance its plans, highlighting the ongoing interest in altcoins. The market's fear and greed index remains mixed, reflecting the uncertain sentiment among investors.
