I personally doubt the possibility of the SEC's Dogecoin ETF approvals despite Elon Musk influence on the current regime of Donald Trump. There are many utility token ETF applications before SEC, i am completely not sure of any meme coins ETF will be approve.
I think the utility tokens that had applied for ETF, like XRP, Sol, not sure if Ada has applied, but XRP and Sol may get ETF registrations approval in near future, being part of the US strategic reserve coins/token that was listed.
