Imagine you found a number one trading platform and end up having to dilute your stake by a factor of 2 (or more likely) within a week because of a meme stock. I actually feel bad for the founding members at RH.
This is temporary relief for people who have totally uninsured crypto on RH. If RH fails, all the crypto disappears. You can't move crypto off of RH to a personal wallet and if you sell to get it off, you take a ~30% tax hit.
