Calling Bitcoin the 'biggest bubble in human history', eminent economist Nouriel Roubini predicted that the virtual currency - currently on a tailspin that erased nearly $500 billion of market value over the past month - will crash to zero value.
Roubini, also known as 'Dr Doom' for accurately predicting the 2008 financial crisis warned that some people would use a market manipulation tactic known as wash trading to prop up the price.
Wash trading in the crypto world involves someone buying and selling their own order to manipulate markets.
A professor of economics at Stern School, part of the New York University, Roubini has been sceptical about Bitcoin since its inception, calling it a "gigantic speculative bubble."
