Robinhood is good for some things (ease of use, commission-free access to stocks and ETFs) but very bad at others, like extremely basic functionality and no dividend reinvestment program (likely because they make money off of your cash accounts like most brokers).
What are you trying to do with your money? Is your retirement savings in a good place? Is your investment horizon short-term, very long, or somewhere in between? Are you comfortable with the (much) greater amount of risk involved in buying individual stocks for the promise of potentially better returns?
If you don't have a solid long-term savings/retirement strategy or little-to-no savings at all, it's not recommended that you put gobs of money on individual stocks and
you should start here instead. If you're comfortable with your long-term savings plan and are flush with cash, Robinhood might be fine if you're looking for a roller coaster ride. Or get into cryptocurrency if you hate yourself.
