Katalin Tischhauser, Director of Research and Investment at Sygnum Bank, said in a statement to Jinse Financial that the chances are slim for the launch of cash ETFs for Solana, Cardano, and other cryptocurrencies in the United States. Even if launched, it may be difficult to attract investors for two main reasons: 1. The U.S. Securities and Exchange Commission (SEC) requires a trading platform that can be effectively monitored by the market for approval of ETFs, but there is no such platform for alternative currencies like Solana, making the SEC unable to ensure market fairness, transparency, and non-manipulation; 2. Compared to Bitcoin and Ethereum, investor demand for ETFs for alternative currencies like Solana is low. This can be observed by comparing the managed assets of Grayscale for Solana (GSOL) and Ethereum (ETHE), where GSOL's assets are only 1.2% of ETHE's, indicating limited investor interest.
