Internet reports, Decrypt reported that Sergei Potapenko and Ivan Turõgin, the Estonia co-founders of HashFlare cryptocurrency mining company, received a notice from the U.S. Department of Homeland Security (DHS) asking them to leave the United States "immediately" or face law enforcement action. The order directly conflicts with a court order requiring them to remain in King County, Washington. The two men pleaded guilty in February this year, admitting fraud through a fake cryptocurrency mining contract and agreed to confiscate approximately US$400 million in assets.
