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