In recent days, Bitcoin's price has shown significant volatility and an overall downward trend. It has been oscillating in the range of $86,000 to $88,000, lacking clear upward momentum.

Recently, Bitcoin's performance has clearly shown signs of fatigue, with a noticeable downtrend in the continuation of the decline. After a sharp drop earlier, the rebound has been weak, and market confidence is lacking, with cautious sentiment spreading. Against the backdrop of macroeconomic uncertainty and a lack of breakthrough catalysts, it is highly likely that the downward trend will continue, and caution against risks is needed to cut losses in a timely manner.

Tesla is facing numerous challenges recently. Its stores, vehicles, and charging stations have become targets of vandalism in various locations globally, with at least 9 states in the U.S. reporting related incidents, and there have also been resistance activities in Europe, impacting its brand image. New car registrations in the EU market dropped by 49% year-on-year from January to February, with market share falling to 1.1%. On March 20, over 46,000 Cybertrucks were recalled, exposing concerns about quality management. However, Tesla also has some positive aspects, such as the nationwide delivery of the refreshed Model Y, further enhancing product strength, and significant discounts on the Model 3, attracting many consumers. Overall, though, Tesla's stock price has fallen more than 50% from its peak in December last year, and Musk's wealth has shrunk by over $100 billion.

Nvidia released the 572.83 WHQL graphics driver on March 18, adding support for the RTX 50 series laptops, providing initial or enhanced support for multiple games, and fixing several issues. However, its stock price has continued to fluctuate this year, with a single-day drop of nearly 17% on January 27, resulting in a market value evaporating by nearly $600 billion. Additionally, new energy efficiency regulations for advanced chip usage have been implemented in China, and Nvidia's H20 chip customized for China does not meet the requirements, putting domestic companies in a dilemma regarding procurement, which has also impacted its business.
