FT voted the most mysterious billionaire of our time. It turned out to be Peter de Potron, whose fortune is estimated at 10-12 billion dollars. The publication notes that there is not a single photograph of the billionaire in the media, as he appears everywhere "like a spy" - in a hat, raincoat and dark glasses, regardless of where he is - inside and outside. In meetings, he demands that people not use any technology and bring "only a notepad and a pencil."
