My guest on this episode is Joshua Greenwald, the CEO of a newly formed crypto derivatives exchange, LXDX. But the part that got me keen to speak with Josh, was the fact that he was a professional trader for more than 10-years prior… Josh started his career at DRW Trading in Chicago, he then left after six years and went on to co-found Greenlight Trading—a proprietary firm specializing in low-latency options market making, almost exclusively for Asian markets. Greenlight grew to be a team of approximately 30-people, before it was acquired. Over the next hour or so, we spoke a lot about Greenlight; the timeline from beginning development up to beginning to trade, the signals and the opportunities that they went after, and even the technology that they utilized (i.e. custom built FPGA chips). Towards the end, we discuss what’s involved in starting an exchange, the functionality and features that are missing from most crypto exchanges but common in traditional markets. And how LXDX is using a security token offering for additional funding (not an endorsement).
