Katalin Tischhauser, director of research and investment at Sygnum Bank, said in an interview with Jinse Financial that the chances of launching cash ETFs for Solana, Cardano, and other cryptocurrencies in the United States are fundamentally low. Even if they are 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 to approve ETFs. However, there is no such platform for alternative currencies like Solana, which makes the SEC unable to ensure market fairness, transparency, and non-manipulation; 2. Compared with Bitcoin and Ethereum, the 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 the asset size of GSOL is only 1.2% of the size of ETHE, showing limited investor interest.
