21Shares has submitted an amended S-1 filing to the U.S. Securities and Exchange Commission (SEC) for a spot Dogecoin ETF, which will trade under the ticker TDOG on Nasdaq. This move comes as Dogecoin's price stabilizes around $0.201, maintaining support above $0.18 after a recent decline. The cryptocurrency is currently trading within a long-term symmetrical triangle, with resistance at $0.25. Despite the ETF filing, on-chain data indicates $10.9 million in net outflows on October 20, suggesting weak spot demand. A favorable SEC decision on the TDOG ETF could enhance Dogecoin's standing in regulated markets, marking a significant milestone as the first spot Dogecoin ETF.
