Robinhood’s Founder on Limited Access

"As a brokerage firm, Robinhood has many financial requirements, including SEC net capital obligations and clearinghouse deposits. Some of these requirements fluctuate based on volatility in the markets and can be substantial in the current environment.“

Still no clarification on what “limited access” actually means. Existing users can buy? 1 share/ person?

It’s one thing to not be transparent about your company’s finances but another to be vague about what, exactly, your users can and can’t do.
