Veteran investor Jim O'Shaughnessy has challenged crypto asset manager Morgan Creek Digital to a bet that would pit the performance of an O'Shaughnessy Asset Management’s strategy against that of the Morgan Creek digital asset index fund. O'Shaughnessy was responding to an initial challenge from Morgan Creek Digital's co-founder and partner Anthony Pompliano, who took to Twitter last week to ask if anyone wanted to bet against his fund beating the S&P 500 index over the next 10 years.
