币界网报道:Bitwise has updated its filings for spot exchange-traded funds (ETFs) tracking Dogecoin (DOGE) and Aptos (APT), signaling potential expansion of its crypto ETF offerings. The asset manager amended its initial filings with the U.S. Securities and Exchange Commission (SEC) to include these altcoins alongside Bitcoin and Ethereum. While the SEC has approved Bitcoin ETFs, it remains unclear whether similar products for other cryptocurrencies will gain regulatory approval. Bitwise's move comes as part of broader industry efforts to diversify crypto investment vehicles. Meanwhile, Grayscale Investments has submitted a new S-3 registration statement for its Bitcoin Trust (GBTC), allowing for potential "in-kind" redemptions. This follows the SEC's recent approval of spot Bitcoin ETFs, which has prompted issuers to refine their product structures. The developments highlight ongoing institutional interest in regulated crypto investment products despite market volatility.
