Katalin Tischhauser, head of investment research at Sygnum Bank, said in an interview that Solana, Cardano, and other cryptoassets are less likely to launch spot ETFs in the United States, and even if they do, they may struggle to attract investors for two main reasons: 1. The US SEC requires that approved ETFs must have a trading platform for market monitoring, but the lack of such a platform for counterfeit products such as Solana makes the SEC unable to ensure that the market is fair, transparent and free from manipulation; 2. Compared to Bitcoin and Ethereum, investors have lower demand for ETFs for counterfeit products such as Solana. This can be seen by comparing the asset management scale of Grayscale's Solana Trust (GSOL) and Ethereum Trust (ETHE). The asset size of GSOL is only 1.2% of ETHE, indicating limited investor interest.
