I also recommend Robinhood's full 123-page Letter of Acceptance, Waiver and Consent. Very readable, and it's quite the catalogue of, at absolute best, less than competent behaviour. https://www.finra.org/sites/default/files/2021-06/robinhood-...
Just the first few pages are enough to convince me that Robinhood is a very poorly run organisation. As a financial technologist with a couple of decades' experience, basic things such as only having a 'physical inaccessibility' BCP plan is appalling.
I wouldn't touch this company with a penny of my money, whether as a customer or an investor.
They're a FinTech firm and they didn't plan for technology outages but did for stuff like weather events? That's just crazy and noob-level planning.
