Ruja Ignatova vanished from an Athens-bound flight in October 2017, days after a warrant was issued for her arrest, and has not been seen since. She had built OneCoin, a cryptocurrency that turned out to run on no real blockchain at all, into a scheme that pulled in billions of dollars from investors across Europe, Asia, and beyond. This BBC World Service film picks up the hunt years after the original Missing Cryptoqueen investigation, following journalists and law enforcement sources chasing new leads on whether Ignatova is dead, in hiding, or under the protection of powerful allies. Interviews with investigators, victims who lost their savings, and people who knew her track the money through shell companies and the FBI's continuing pursuit of her associates. The film weighs competing theories, including reports linking her to organized crime figures, without settling on a single answer. It closes with the case still open and Ignatova still on the FBI's most-wanted list, one of the largest fraud suspects never brought to trial.
