币界网报道：Bitwise Asset Management has submitted a revised filing with the U.S. Securities and Exchange Commission (SEC) for spot exchange-traded funds (ETFs) tracking Dogecoin (DOGE) and Solana (SOL). The updated proposal follows the firm's initial filing in June 2024, which sought approval for similar crypto-based ETFs. Bitwise's Chief Investment Officer Matt Hougan emphasized the growing institutional demand for diversified crypto exposure beyond Bitcoin and Ethereum. The filing outlines plans for the ETFs to hold the underlying cryptocurrencies directly, with Coinbase Custody serving as the custodian. This move comes amid increasing regulatory scrutiny of meme coins like Dogecoin, while Solana continues gaining traction as a high-performance blockchain platform. Industry analysts note Bitwise's revised application could signal broader acceptance of altcoin ETFs if approved, though the SEC has historically been cautious about expanding crypto investment products beyond Bitcoin-focused offerings.
