If we look at how long e been take the SEC to approve Bitcoin spot etf in the United States, you go know say Altcoins ETF no go happen overnight, if at all e go happen. I don't think there is enough request for either Ethereum, XRP (or any other altcoin) spot etf in the United States, na just as dem approve Bitcoin spot ETF i begin see news wey dey talk say na altcoins be next.
Having said that, make we watch wetin go happen, but you know say altcoins dey more risky than Bitcoin, because many of them no get use cases, so i think the SEC go dey very reluctant to approve any altcoin ETF.
You're very observant Legendary, I believe SEC will find it difficult to approve ETFs on altcoins because they know that they don't have high volatility as Bitcoin and besides most people who are investing in altcoin do so in other for it to pump then they sell off their coins unlike Bitcoin that people buy and hodl for a long period of time without selling off their coins so Bitcoin is more sustainable as compared to any other altcoins so even if SEC will grant ETF approval to any other altcoins, it will definitely take them longer time even more than the time it took them to approve spot bitcoin ETF.
