Bitcoin biggest bubble in history, says economist who predicted 2008 crash

Nouriel Roubini calls cryptocurrency the 'mother of all bubbles' as it falls below $8,000

The economist credited with predicting the 2008 global financial crisis said a 12% fall in the value of bitcoin on Friday was the latest proof that the cryptocurrency was the biggest bubble in history and destined for a crash.

Nouriel Roubini, professor of economics at New York University, said bitcoin was "the mother of all bubbles" favoured by "charlatans and swindlers" as it fell below $8,000 (5,600) early on Friday, marking a 30% drop since the beginning of the week as investors became increasingly twitchy about a clampdown on cryptocurrencies by regulators. Later it rallied, climbing back over $8,600 by 3pm (GMT).
