The digital currency Bitcoin is too “libertarian” and reliant on an “Ayn Rand schtick,” Hillary Clinton campaign chairman John Podesta said in an exchange with campaign tech aide Teddy Goff published by WikiLeaks on Tuesday.

Podesta made the statement after meeting Stan Stalnaker, a founding director and chief strategy officer for the digital currency “Ven,” at a Clinton fundraiser in London. Stalnaker followed up with a May 13, 2015, email to Podesta pitching Ven as an option for the campaign.
