Oxford-educated, "Forbes cover" and covered in jewels... Dr Ruja Ignatova promised to revolutionize the financial world (and make you very rich!) with her crypto-currency OneCoin.

After being arrested by the FBI, her brother Konstantin Ingnatov has now pleaded GUILTY to fraud and conspiracy. As for Dr. Ruja Ignatova? She hasn't been seen since 2017....
