According to Eric Balchunas, 21Shares has officially filed for a Dogecoin ETF, marking a significant milestone for DOGE and the broader cryptocurrency market. This ETF filing signals growing institutional interest in meme coins and could drive increased liquidity and trading volume for Dogecoin if approved. Traders should monitor regulatory developments closely, as the approval or rejection of this ETF may trigger substantial volatility in DOGE prices and influence sentiment across altcoins. This move follows previous spot Bitcoin and Ethereum ETF launches, indicating an expanding appetite for regulated crypto investment vehicles (source: Eric Balchunas, Twitter, May 28, 2025).
