In a remarkably frank talk at a Bank of England conference, the Managing Director of the International Monetary Fund has speculated that Bitcoin and cryptocurrency have as much of a future as the Internet itself. It could displace central banks, conventional banking, and challenge the monopoly of national monies.  

Christine Lagarde–a Paris native who has held her position at the IMF since 2011–says the only substantial problems with existing cryptocurrency are fixable over time. 

In the long run, the technology itself can replace national monies, conventional financial intermediation, and even "puts a question mark on the fractional banking model we know today."

In a lecture that chastised her colleagues for failing to embrace the future, she warned that "Not so long ago, some experts argued that personal computers would never be adopted, and that tablets would only be used as expensive coffee trays. So I think it may not be wise to dismiss virtual currencies."
