It’s not hard to draw similarities between Elizabeth Holmes of Theranos infamy and Ruja Ignatova — the brilliant Bulgarian-German scam master behind the OneCoin swindle, history’s second biggest fraud after Bernie Madoff’s $65 billion Ponzi con.

Both were charismatic star students with huge ambitions who used charm and good looks to convince people to throw fistfuls of money at their sketchy start-ups. Each also hooked up with a male lover who helped them rip off millions from dupes.
