Bitmain Under Federal Investigation The U.S. has been quietly running “Operation Red Sunset” — probing whether Bitmain’s mining rigs can be remotely controlled or used for surveillance. DHS reportedly tore apart chips, firmware, even tested units at ports. This comes right after American Bitcoin (backed by Eric & Don Jr.) bought 16,000 Bitmain miners for $314M. Senate intel reports are calling the hardware “an unacceptable risk” near critical infrastructure. Bitmain denies everything.
