This is the problem, if Ethereum is accepted into the ETF then there is a possibility that other altcoins will enter the ETF, of course this will pose a greater risk because altcoins have a very high risk and altcoins have price movements depending on the project being developed, if The ETF has accepted altcoins and after that the project developed in this altcoin collapsed, which will make the SEC pay for the decisions they made and of course this is very detrimental for them.
ok I understand what you're saying, but there are altcoins that are really crap, like Doge
It's not just me who says it but the creator of Doge himself also says it, which is not a serious coin
now I stay well away from Doge and I would stay well away from an ETF on Doge assuming it comes out
remember the companies that make ETFs don't risk money but they risk their faces, an ETF on Doge will never exist
