The U.S. Securities and Exchange Commission (SEC) has approved two new altcoin ETFs, set to begin trading following the November 21 decision. This marks a regulatory shift beyond Bitcoin and Ethereum, as investor interest in altcoin exposure grows. Bloomberg analyst Eric Balchunas predicts the Dogecoin ETF could see $11 million in first-day trading, while Grayscale's Chainlink Trust awaits a decision. Canary Capital's XRP ETF recently recorded $59 million in day-one trading, underscoring the strong demand for regulated altcoin products. Grayscale, already offering Bitcoin, Ethereum, and Solana ETFs, is expanding its portfolio with DOGE and XRP. Meanwhile, REX Shares and Osprey Funds launched Dogecoin ETFs in September, increasing market competition. November has emerged as the busiest month for altcoin ETF approvals.
