His deep insight into macro context for equities and crypto - as well as his multivalent and diligent assessment of trends, opportunities and risks, are incredibly timely and well-reasoned. I especially appreciate that he has a robust machine learning approach, but isn’t a slave to it. He regularly gives a seasoned evaluation that combines the technicals, the fundamentals, as well as the digital signals – with an appropriate concern for risk management. '
