A U.S. federal judge has issued a temporary restraining order (TRO) against crypto trading and lending firm BlockFills, freezing bitcoin assets tied to an ongoing lawsuit filed by investment firm Dominion Capital. The court order, filed March 3 in the U.S. District Court for the Southern District of New York, prevents BlockFills from transferring or disposing of 70.6 bitcoin allegedly belonging to Dominion while the legal dispute proceeds.
