If the exchange is not trading against its customers, and it is only custodying customer funds and collecting fees, how does it regularly acquire 20 million dollars of shitcoin exposure? Here's one way a crypto exchange could work: - many users deposit coins and fiat - some of those users are market makers - the users trade with each other - the exchange just custodies the coins and fiat and collects fees - the exchange does not need to send customer funds to another exchange because it is not assuming twenty million dollars of directional risk Can you explain your understanding of how it should work instead? Can you explain why people with these roles work at an exchange, an entity that does not engage in systematic trading or take on any nonzero amount of directional risk ever? https://www.linkedin.com/in/chen-x-74a83322/ https://www.linkedin.com/in/chen-x-74a83322/ https://www.linkedin.com/in/wanghan https://www.linkedin.com/in/wanghan https://www.linkedin.com/in/nicolasbourdrez/ https://www.linkedin.com/in/nicolasbourdrez/ https://www.linkedin.com/in/ronaldyiap/ https://www.linkedin.com/in/ronaldyiap/ https://www.linkedin.com/in/ernest-lim-88529b135/ https://www.linkedin.com/in/ernest-lim-88529b135/ https://www.linkedin.com/in/pravin-pathmanathan/ https://www.linkedin.com/in/pravin-pathmanathan/ https://www.linkedin.com/in/jin-marcus-wang/ https://www.linkedin.com/in/jin-marcus-wang/ https://www.linkedin.com/in/calen-zeng-b3324a196/ https://www.linkedin.com/in/calen-zeng-b3324a196/ https://www.linkedin.com/in/zzhuaj/ https://www.linkedin.com/in/zzhuaj/ https://www.linkedin.com/in/yining-liu-763a5041/ https://www.linkedin.com/in/yining-liu-763a5041/ https://www.linkedin.com/in/yu-tao-930721/ https://www.linkedin.com/in/yu-tao-930721/ https://www.linkedin.com/in/tom-chan-812b4090/ https://www.linkedin.com/in/tom-chan-812b4090/ https://www.linkedin.com/in/mark-amsellem-71a1a132/ https://www.linkedin.com/in/mark-amsellem-71a1a132/ https://www.linkedin.com/in/oliver-jieren-jia-636166b6/ https://www.linkedin.com/in/oliver-jieren-jia-636166b6/ Can you explain why they are hiring for these HFT/systematic trading roles? https://www.linkedin.com/jobs/view/3262469829/ https://www.linkedin.com/jobs/view/3262469829/ https://www.linkedin.com/jobs/view/3254166615/ https://www.linkedin.com/jobs/view/3254166615/ https://www.linkedin.com/jobs/view/3104863804/ https://www.linkedin.com/jobs/view/3104863804/ Thanks.
