Ruja Ignatova was born in Sofia, Bulgaria in 1980, before moving to Germany with her family when she was ten. In 2005 she was awarded a doctorate in law from the University of Konstanz. She went on to work for management consultancy McKinsey & Co in their eastern European office. In 2014 Ignatova set up OneCoin, which she claimed was a cryptocurrency that would become a “bitcoin killer”, and began promoting the currency at large public conferences around the world, including one at Wembley Stadium.
