I'm confused about how to reply to a post like this and I'm also not an expert in guessing. The fact is that until now Solana has not been approved by ETF, isn't that right?
My assumption is, it seems like ETF has very strict regulations for Solana coins to be approved so that it takes longer to be approved. Not to mention the story of Solana which once plunged after the collapse of the FTX Exchange, even though it has risen again, bad memories like that still haunt the Solana coin.
One more thing, as far as I know, the Solana blockchain often goes out and maybe this is what makes Solana considered to be accepted by ETF. Cmiiw
