One of the most famous bitcoin critics. His predictions are always spot on, be careful, bitcoin is only for terrorists and governments should print money to "save the economy" (Offer a blood sacrifice to the almighty altar of aggregate demand.)
(Never forget that they gave this guy a Nobel Prize in economics 10 years after he said this nonsense. The titles don’t matter, the made up math doesn’t matter, Paul Krugman is guaranteed to say something dumb again.)
