On July 12 (UTC+8), Grayscale sent a letter from its lawyers to the U.S. Securities and Exchange Commission (SEC) regarding the listing of its multi-token ETF, which includes Bitcoin, Ethereum, Solana, $XRP, and Cardano, on the New York Stock Exchange Arca. The letter alleges that the SEC's suspension of the fund's listing is causing "harm to investors." Grayscale claims it was approved on July 1, but the SEC subsequently requested further review and halted the listing. Grayscale warned that it may file a lawsuit to force the SEC to release the listing as soon as possible, and emphasized that the SEC should not use internal processes to circumvent the timely approval or rejection regulations set by Congress. The incident highlights that despite the Trump administration's relaxation of crypto regulation, multi-asset crypto ETFs still face severe scrutiny in the United States. [MetaEra]
