Yeah, the possibility of more ETF is almost certain, it is a significant effect of the US new regime lead by president Donald Trump, the most crypto friendly president. I think from several news making rounds the crypto space, we may see Solana, XRP, Litecoin and others in near future.
However, Litecoin is currently pushing hard to get the SEC approval but XRP may come before the other ETF applications.
Generally speaking, we may expect more ETF applications, even meme coin ETF registrations was the new few weeks ago, however there could be more ETF, and SEC approvals before the end of Donald Trump's regime.
