A BBC investigation into the fate of Ruja Ignatova, the flamboyant founder of fake cryptocurrency OneCoin...and the world’s most wanted woman.

Dubbed the “Missing Cryptoqueen”, Ruja Ignatova is on the FBI’s Ten Most Wanted Fugitives list after defrauding investors of $4.5 billion and then vanishing. Now, #BBCEye and #BBCPanorama investigate her close ties to a suspected Bulgarian organised crime boss and allegations that she was brutally assassinated.

This #BBCWorldService documentary has exclusive access to the US special agent in charge of tracking Ignatova down and follows a brave Bulgarian journalist who’s faced grave threats trying to get to the truth.

Did the missing Cryptoqueen run with the money, or was she fatally targeted by the very people that were supposed to protect her?
