In this episode I speak with the anonymous twitter user @macrocephalopod. The arc of our conversation follows the arc of his career: beginning with slow-frequency style premia in a hedge fund to building a prop desk that trades mid-to-high frequency strategies in crypto. A large part of the conversation can be characterized as comparing and contrasting the roles through the lenses of research, operations, and risk management.  For example, in what ways is long/short equity meaningfully different than long/short crypto?  Or, how important are topics like market impact, fill ratios, and borrow fails in mid- versus slow frequency strategies? While crypto is the venue, I believe the wisdom imparted in this episode spans all markets. Please enjoy my conversation with @macrocephalopod.
