I'm not so familiar with Robinhood so I'm not so sure, but are you able to buy the actual coin? Or is it similar to Etoro where you can't actually transfer it to wallets because you're not actually buying the coins? Its only speculative, like stocks. Its nice to see that there are many interested users however Robinhood had some issues during the GME fiasco a while back so if you plan on buying crypto, then Robinhood may not be your best bet. I guess many traders want in to cryptocurrency because of the current bull market but are not actually keen on owning it.
