Besides, there are also a lot of big entities filing for it, not just BlackRock (although it is the biggest so far).
But I do believed that SEC will approved Bitcoin first before any cryptocurrencies, even Ethereum.
Gary gensler will be more strict about letting the ETH ETF be approved though he already said in one of these statements that ETH is a commodity. It won't be easy for the ETH community but it is true that if the bitcoin ETF gets approved ETH will be as well eventually. There are other big asset managers who filled out the ETH ETF as well but the community is more focused on Blackrock's ETF approval because they think BlackRock has influence over the whitehouse and it is a green light for the whole industry if their ETF gets approved. This is positive news but we should not be overly excited as the market will not go straight upward.
