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.
Lew’s skepticism comes just a few months after a Treasury Department official told a Senate panel that bitcoin is a legitimate currency and should not be banned.
In the interview Thursday, Lew warned the government must ensure the currency is not used to help terrorists.
“I think from the government’s perspective, we have to make sure it does not become an avenue to funding illegal activities or funding malign purposes like terrorist activities," he said. "It is an anonymous form of transaction and it offers places for people to hide.”
