Bitcoin's price bubble will burst under government pressure | Kenneth Rogoff

The cryptocurrency is up 1,600% in two years - but state efforts to remove its near-anonymity will undermine its popularity

Is the cryptocurrency bitcoin the biggest bubble in the world today, or a great investment bet on the cutting edge of new-age financial technology? My best guess is that in the long run, the technology will thrive, but that the price of bitcoin will collapse.

If you haven't been following the bitcoin story, its price is up 600% over the past 12 months, and 1,600% in the past 24 months. At over $4,200 (as of 5 October), a single unit of the virtual currency is now worth more than three times an ounce of gold. Some bitcoin evangelists see it going far higher in the next few years.
