Hedge fund billionaire Griffin knocks bitcoin

9:58 AM ET Wed, 18 July 2018

Citadel's Ken Griffin is not a fan of digital currencies and bitcoin. "I don’t have a single portfolio manager [of mine] who has told me we should buy bitcoin, not a single portfolio manager," he said at the Delivering Alpha Conference in New York on Wednesday. "I have a hard time finding myself wanting to be in a position for being a liquidity provider for a product I don’t believe in."
