Sure. First, don't use Robinhood or anything investing related for crypto, because then you don't actually have crypto, you're just betting on it. It's like buying silver ETFs; you don't own any physical silver, you're just betting on it going up in dollar value. You want to buy crypto, not stocks in crypto! If crap hits the fan, then you still dont have crypto, silver, gold, ammo, whatever, so I want to beat that into your head! So use something like coinbase, Zengo, nice hash, or something like that to set up a wallet.

Your wallet is an address that you can think of like a bank account number. You can tell me what your address is and I can send you crypto to pay for goods and services. You need different wallets for different crypto. Etherium, litecoin, bitcoin, etc will all need different wallets. I use zengo on my phone to buy crypto but I also have desktop apps as well.
