Here are today's news in the cryptocurrency world and my views:

1. **Fed officials say they will maintain high interest rates for longer**

Fed officials said at a recent meeting that they will maintain the current high interest rates for longer as inflation data has been below expectations for three consecutive months. Although some officials believe that the current policy is sufficient to curb economic activity and reduce inflation, they are still willing to tighten policy further if inflation risks increase. This news may have a dual impact on the market. High interest rates usually inhibit investment in risky assets, but if investors expect the continuity of interest rate policies, they may remain cautious about the cryptocurrency market.

2. **AI-related cryptocurrencies rise**

Before Nvidia's quarterly earnings report was released, AI-related tokens such as Fetch.ai, Render, Bittensor and SingularityNET rose by 4%-5%. This shows that the market is optimistic about the potential of AI technology in the crypto field. The rise of AI-related cryptocurrencies reflects investors' confidence in the future integration of technology. For investors, this may be a good time to pay attention to projects combining AI and blockchain.

3. **VanEck urges SEC to prioritize its Ethereum ETF proposal**

VanEck's head of crypto research called on the U.S. Securities and Exchange Commission (SEC) to prioritize their Ethereum ETF proposal, and the SEC is expected to rule on the proposal by May 23. If VanEck's Ethereum ETF is approved, it will mark an important milestone in the cryptocurrency market and may attract more traditional financial institutions to enter the crypto market, thereby driving up the price of Ethereum and other mainstream cryptocurrencies.

4. **New revenue sharing model for decentralized exchanges (DEX)**

Uniswap is considering introducing a new revenue sharing mechanism that may allocate part of the transaction fees to UNI token holders. This proposal has received widespread support. This change may make the governance tokens of decentralized exchanges more valuable, attract more investors and users to participate, thereby enhancing the vitality and competitiveness of the entire DEX ecosystem.
