Republican state representative Bill Schuette introduced Bill 4510 on May 21, proposing to amend Michigan's Public Employee Retirement System Investment Act to allow the state treasurer to invest in cryptocurrencies with a market value exceeding $250 million.

An American tourist in the UK was drugged by a fake taxi driver and had $123,000 worth of Bitcoin stolen.

According to My London, Jacob Owen-Klein called an Uber after drinking at a bar in London but chose a private hire taxi that looked similar to an Uber driver but had a different vehicle. It was only after the incident that he realized the difference.

After getting into the car, the driver handed him a cigarette, which may have contained rare and potent anesthetic scopolamine, causing him to lose consciousness quickly. Shortly after waking up, the driver kicked him out of the car, took his phone, and quickly fled, which contained the private keys to his cryptocurrency account.

Although U.S. President Trump has implemented tariff exemptions for semiconductors, the actual significance is limited, as most semiconductors enter the U.S. through complete systems such as servers, GPUs, laptops, and smartphones.

These complete systems still face heavy taxes of up to 49%, and the actual execution of semiconductor exemptions has provided almost no substantial help. For example, Nvidia's DGX systems are not exempt and may face tariffs of nearly 40%. This cost increase may hinder the development of AI infrastructure projects.

The impact of the new tariffs has begun to slow the progress of supply chains, particularly affecting the development of mature generative AI and large language models in fields such as finance and defense.
