Jack Lew: Govt. Needs More Time To Discuss Bitcoin

Treasury secretary says he is incredulous of the "phenomenon"

Treasury Secretary Jack Lew said Thursday the government needs more time to explore the effect of bitcoin, a virtual currency.

"Bitcoin is a phenomenon that we need more time to discuss. I've talked to [JPMorgan CEO] Jamie Dimon about it, and he and I both share some incredulity about the whole phenomenon," Lew said on CNBC Thursday during his visit to the World Economic Forum in Davos, Switzerland.
