Robinhood's real "cash cow" is selling trading information collected from millions of users to the very hedge funds that they claim to protect small retail investors from HF manipulation. It's hard to beat the hedge funds if they have access to both sides of the trading deck on every position on their book. Reminds me of the "Good Ole Days" on the Chicago Board of Trade when all the "pit traders" had the order flows on hand held White Boards!!!!!
