Of course, there are concerns that ETH Spot ETFs will not be approved for many reasons, perhaps the most important of which is that the SEC is looking into classifying Ethereum as a security.
Today I was reading an article on the same topic. In an interview with CNBC on April 9, the CEO of investment firm VanEck says that the SEC is unlikely to approve ETH Spot ETFs. Likewise, the CEO of CoinShares, Jean-Marie Mugnitti, is similarly pessimistic the same thing.
In my opinion, even if there is pessimism and approval seems difficult at the present time, it will come in the end, because large companies including (Grayscale), (BlackRock), and (Fidelity) want to enter and will press with all their might to obtain approval.
