Academics and Bitcoin - a curious mix

On a day when there is a report out about the confused approach of regulators regarding the $200 billion 'cryptocurrency' market another report caught my eye: Academics study the probability that bitcoin's price will fall to zero - in one day! But a similar calculation would be to find the probability that a meteor hits the earth and wipes out all life - interesting but pretty useless. Cryptocurrencies serve those in failed states quite well, in addition to criminals and tax cheats. Use your common sense!
