BlockBeats news, on October 19, according to the Times investigative report, it found bitcoin mining farms owned or operated by Chinese companies in at least 12 states in the United States, with a total energy consumption equivalent to the energy consumption of 1.5 million households, and many mining farms are equipped with Bitmain-made mining rigs. Records show that since May 2021, when China banned Bitcoin mining due to concerns about energy use and economic instability, Bitmain has shipped 15 times more equipment to the United States than in the past five years combined. A recent report by the company claims that it already controls 90% of the global bitcoin mining equipment market. Although there is no clear evidence of connection, the United States still suspects that these mines in the United States are related to Chinese officials.
