The U.S. Securities and Exchange Commission (SEC) recently postponed the approval of several cryptocurrency spot ETFs, including XRP, Solana, Litecoin, and Dogecoin, with some decisions pushed to June 2025 or later. Although the delays have caused short-term market fluctuations, analysts remain optimistic about the eventual approval of these ETFs, estimating the probability of approval to be between 75% and 90%. The SEC's cautious approach reflects the complexity of regulatory classifications for crypto assets, but also shows concern for market stability. As the regulatory environment gradually clarifies, the launch of spot crypto ETFs is expected to provide investors with more diverse investment options.
