If we are to talk about the ETF that is most likely to be approved, I believe it would be an ETF primarily based on Solana (SOL). Why? First of all, Solana's technology has developed rapidly in recent years, and its high throughput and low transaction costs have made it stand out in the market, especially with strong application scenarios in decentralized finance (DeFi) and the NFT sector. Secondly, Solana's ecosystem is continuously growing, with an influx of various projects and developers, making it more 'reliable' than many other altcoins. Compared to some other cryptocurrencies, Solana's stability and innovation may impress the SEC more.

If the Solana ETF can be smoothly approved, it would indeed be an important breakthrough for the cryptocurrency market, marking the entry of more mainstream and regulated digital assets into the traditional investment space. As for the SEC's caution, I believe it is precisely to avoid market overheating and regulatory lag, to protect investors' interests, and to prevent these emerging assets from bringing unforeseen risks to the market. Once this process breaks through, it will mark the beginning of an investment opportunity.
