Placing orders is not rocket science. I bought my first stock on etrade decades ago as a teenager from a lower class family. RH didn’t add much except a pretty UI and lubrication to make it more gamboling than it already was.
E-Trade, you mean the company that depicted a baby earning a stack of cash in a Superbowl ad?
Good anecdote and I'm glad you were able to figure out how to buy your first stock, but even the gambling community cried foul on E-Trade when it was brand new.
Robinhood's mobile app is known for its simple UI and improved charts over ET; it's much less cluttered in addition to being a good deal for taxable accounts + offering crypto derivatives.
