Elizabeth Warren: Foreign mining companies are a threat to U.S. security

“In addition to direct environmental damage from cryptomining facilities, such companies pose a threat to national security and can be used to spy on and collect data on the U.S. energy sector, the availability of energy resources, and the organization of electricity supply chains,” Warren said.
The senator cited figures from The New York Times that Chinese-owned U.S. mining companies consume enough electricity to power more than 1.5 million households. National security experts have long warned the government that connecting foreign-owned cryptomining companies to the U.S. power grid could leave it vulnerable to malicious blackouts and cyberattacks.
Elizabeth Warren believes that foreign nationals could secretly buy up mining businesses in the United States, paying for them with cryptocurrency.

“Cryptocurrency allows us to bypass our traditional banking system and anti-money laundering rules that are supposed to prevent any anonymous foreign money from coming into the United States. In fact, that's how a Chinese investor was able to secretly buy a $6 million mining farm a mile from a strategic missile base that housed intercontinental ballistic missiles,” Warren said.
In May, U.S. President Joe Biden issued an executive order banning Chinese mining company MineOne Partners from disposing of real estate near an Air Force base in Wyoming.
