FT voted the most mysterious billionaire of our time. This is Peter de Potron, whose net worth is approximately $10 to $12 billion. The magazine notes that there is not a single photograph of this billionaire in the media, as he appears "like a spy" - always wearing a hat, raincoat and sunglasses, regardless of the location, whether it is on the street or indoors. In meetings, he often demands that all gadgets be given up and that "only a pad and pencil" be brought.
