The rise of Bitcoin and its integration into the U.S. economy has sparked concerns over potential security risks, particularly from China's dominance in the Bitcoin mining industry. Experts warn that Chinese-manufactured mining hardware could contain hidden security backdoors, potentially allowing cyber-espionage or even remote sabotage of critical infrastructure. To mitigate these risks, calls are being made for stricter regulations, increased supply chain transparency, and the development of a robust U.S. Bitcoin mining sector. Some also suggest banning Chinese-manufactured mining hardware in the U.S., similar to the ban on Huawei for 5G networks.
