I would reach out to two sorts of people. 1) traders who already trade other products, especially quant traders and traders of exotic derivatives. 2) young people who are part of trading clubs at high-tech universities where there are likely to be some computer scientists in the mix. Basically, I would structure the desk such that the technologically savvy people are analysts to the risk savvy people, with some quants to assist them and conceive pricing/predictive tools. Your average quant is likely to know a lot about the financial markets, and have the ability to learn about individual crypto coins, but also likely to be unaccustomed to discretionarily managing risk. I don't know how you would find someone who has been successful in trading bitcoin, but that would probably have more to do with luck than skill anyway. Not to mention that a large component of successfully trading on a desk involves communication with others, and that is larger than just "was this guy able to make money by being long bitcoin in 2017."
