Nobel Prize-winning economist Joseph Stiglitz said “bitcoin is successful only because of its potential for circumvention, lack of oversight.”  

“So it seems to me it ought to be outlawed,” Stiglitz said Wednesday in a Bloomberg Television interview with Francine Lacqua and Tom Keene.

“It doesn’t serve any socially useful function.”

Bitcoin surpassed $11,000 in a matter of hours after hitting the $10,000 milestone, taking this year’s price surge to almost 12-fold as buyers shrugged off increased warnings that the largest  digital currency is an asset bubble.

“It’s a bubble that’s going to give a lot of people a lot of exciting times as it rides up and then goes down,” Stiglitz added.
