The SEC recently postponed the approval of five cryptocurrency ETFs, a decision that isn't particularly surprising. The SEC is known for its caution, especially when it comes to volatile assets like altcoins, and their stance has always been careful. After all, they are more concerned that the entire cryptocurrency market is still not stable enough, and the regulatory framework has not fully caught up. However, if I had to say which ETF is most likely to be approved, I believe it would be one that focuses 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 fields of decentralized finance (DeFi) and NFTs which have 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 be more appealing to the SEC. If the Solana ETF can be successfully approved, it would truly represent a significant breakthrough for the cryptocurrency market, marking the entry of more mainstream and regulated digital assets into traditional investment domains. As for the SEC's caution, I believe it is precisely to avoid market overheating and regulatory lag, protecting investors' interests and preventing these emerging assets from bringing unforeseen risks to the market. Once this process breaks through, it signifies the opening of an investment opportunity. I hope the SEC will expedite the process and provide the market with a clear direction.
