I've been investing since I was 10 years old. I opened accounts at the top ten most popular brokerages in search of the very best custodian for my IRAs. The best brokerage for IRAs is Fidelity. Fidelity is a world-class financial institution. Unlike Robinhood, Fidelity doesn't sacrifice functionality for excessive simplicity. Fidelity offers every type of financial account and access to almost every asset class. If you started your investment journey using Cash App and Robinhood, that's fine. However, as you learn more, you will quickly outgrow Robinhood. Fidelity is a brokerage for grownups. Once you start to explore what Fidelity has to offer, Robinhood will look like a joke in comparison.
