The missing 'crypto queen' listed among FBI's 10 most wanted for scamming investors and disappearing with their millions was killed on a yacht five years ago, it has been claimed.
Bulgarian-born German citizen Dr Ruja Ignatova, 42, made headlines when she invented the cryptocurrency OneCoin, which she marketed worldwide, attracting investors from far afield.
Backers then ploughed a total of around €4 billion (£3.40 billion) into OneCoin, before Ignatova disappeared and took all the money with her in 2017.
