Someone asked me: If you're running an exchange, just run an exchange; if you're running a brokerage, just run a brokerage. Why insist on putting 'crypto contracts' and 'US stocks' on the same platform? Because users have already been living this way. Almost everyone around me trading crypto also holds US stocks; friends buying US stocks have secretly allocated some BTC too. It's the products that are stuck in the past, forcing them into two separate groups. I want to tear down this wall.
