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