I'm considering investing in cryptocurrencies and I've heard about Robinhood as a popular platform. However, I'm still not sure if I can actually purchase crypto on Robinhood. Could you please clarify if Robinhood allows users to buy and sell cryptocurrencies? If so, what are the main cryptocurrencies they offer? Additionally, are there any limitations or restrictions I should be aware of before making a purchase? Understanding the platform's capabilities and any potential limitations would help me make an informed decision about whether Robinhood is the right place for me to invest in crypto.
