I definitely believe this are huge news not only for ETH but the space... But specifically for ETH I believe several things will happen, first this is an important step towards the creation of an ETH ETF, also this will be quite reassuring for a lot of big investor on their current digital investments, perhaps lead them to diversify a bit more confidently as well help inject some more fiat in the space.
The ethereum network has used by so many companies to provide and develop the future infrastructure to support and minimize the cost of their business. It looks like ether gonna be another huge platform in the future. That means US investors will able to buy more ethereum safely. And i like that. that's a huge news.
