Everyone's talking about how Robinhood sells your orders to Citadel. As important is how they make money lending out your stonks and cash, but give you nothing for it. Like your bank lending out ur cash and paying you no interest. That's what's happening. But its "free" they said

56% of Robinhood's customers owned Gamestonk. At the height of the gamma squeeze, RH was lending all of these Gamestonk shares to short-sellers for 50% APY. They made bank lending your shares to the short-sellers, paid you $0, then halted your purchases so shorts could pile-on.

But it's "free" bro, they are "democratizing" trading.
