The current progress of Sino-US trade negotiations may have indirect but far-reaching effects on Circle B (the blockchain and cryptocurrency industry). On one hand, if breakthroughs are made in the negotiations and tariff barriers are reduced, it could promote Sino-US technological cooperation, including cross-border applications and investment flows in blockchain technology. On the other hand, if negotiations become stalled, the US may further tighten technology export controls, affecting Chinese blockchain companies in critical areas such as chips and cloud computing supply chains. Additionally, China's countermeasures on key resources like rare earths may impact the global high-tech industry, including the manufacturing of cryptocurrency mining equipment. Therefore, investors in Circle B need to closely monitor the negotiation dynamics, especially regarding terms related to technology restrictions and financial policies, in order to respond to potential market fluctuations.
