據彭博社報道，美國多部門對比特大陸（Bitmain）展開了為期數月的國家安全調查，重點評估其比特幣礦機是否可能被中國遠端操控，用於情報收集或破壞關鍵基礎設施。此次調查源於去年一項聯邦安全審查，當時比特大陸設備在靠近美軍基地的礦場中被視為「重大國家安全風險」；今年7月，參議院情報委員會亦指出其礦機可能存在「可被操控的漏洞」。對此，比特大陸否認所有指控，聲稱不存在遠端控製能力，且嚴格遵守美國法律。

According to a Bloomberg report, multiple U.S. agencies have launched a months-long national security investigation into Bitmain, focusing on assessing whether its Bitcoin mining machines could be remotely controlled by China for intelligence collection or sabotaging critical infrastructure. This investigation stems from a federal security review last year, when Bitmain's equipment in a mining farm near a U.S. military base was deemed a 'significant national security risk'. In July this year, the Senate Intelligence Committee also pointed out that Bitmain's mining machines may have 'exploitable vulnerabilities'. In response, Bitmain denied all allegations, claiming that it has no remote control capabilities and strictly complies with U.S. laws.
