A mystery blonde “crypto coach” who was travelling with Telegram CEO Pavel Durov cannot be located by her family following the secretive tech billionaire’s arrest in France this weekend.As reported by the New York Post, Juli Vavilova, 24, who is also a video game streamer, is at the centre of online speculation after she shared a series of glam pictures on social media while apparently travelling with Durov to Azerbaijan last week, according to matching social media posts highlighted by French privacy data researcher Baptiste Robert and others.Online observers suggest those posts may have given away details about the exiled Russian mogul’s movements prior to his arrest. He was taken into custody after his private jet landed at Le Bourget airport outside Paris on Saturday.
