What Crypto can you buy on Robinhood?

So, I'm curious about the cryptocurrency offerings on Robinhood. I've heard they've expanded their list quite a bit, but I'm not entirely sure what all I can buy there. Could you provide a brief overview of the cryptocurrencies that are currently available for trading on Robinhood? Specifically, I'm interested in knowing if they offer popular coins like Bitcoin, Ethereum, and Litecoin, as well as any other notable altcoins that might be worth looking into. Additionally, I'd like to know if there are any restrictions or limitations in terms of trading volumes or types of transactions. Any insights you have would be greatly appreciated!
