According to a regulatory filing on August 9, U.S. regulators said they need more time to decide whether ETFs designed as one-stop cryptocurrency portfolios can be listed on the Nasdaq electronic stock exchange. The filing is a response to Nasdaq's June request for permission to list the Hashdex Nasdaq Crypto Index ETF on its electronic exchange. If approved, the Hashdex Nasdaq Crypto Index ETF will become the first diversified spot cryptocurrency ETF in the U.S. market. It will also be the first U.S. ETF to hold alternative cryptocurrencies, or "altcoins." (Cointelegraph)
