If we are to discuss the ETF that is most likely to be approved, I believe it would be an ETF primarily based on Solana (SOL). Why? Firstly, Solana's technology has developed rapidly in recent years, with its high throughput and low transaction costs allowing it to stand out in the market, especially in the decentralized finance (DeFi) and NFT fields where it has strong application scenarios. Secondly, Solana's ecosystem is continuously expanding, 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 resonate more with the SEC.
