Users can trade without paying traditional brokerage fees and can invest in fractional shares, allowing them to buy portions of expensive stocks. Unlike its competitors, Robinhood provides unique features like IPO access and a premium subscription service called Robinhood Gold for advanced trading. The company's goal is to democratize finance and empower individuals to take control of their investments.
