[Sygnum Bank Director: Solana, Cardano and other crypto assets are less likely to launch spot ETFs in the United States] Golden Finance reported that Katalin Tischhauser, director of investment research at Sygnum Bank, said in an interview that Solana, Cardano and other crypto assets are less likely to launch spot ETFs in the United States, and even if they are launched, they may find it difficult to attract investors. There are two main reasons: 1. The US SEC requires that approved ETFs must have a trading platform for market monitoring, but there is a lack of such a platform for altcoins such as Solana, which makes it impossible for the SEC to ensure that the market is fair, transparent and not manipulated; 2. Compared with Bitcoin and Ethereum, investors have lower demand for ETFs for altcoins such as Solana. This can be seen from the comparison of 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, showing limited investor interest.
