Yes, I think this point has to be emphasised more. Some people see the nft world to be so different .
As you rightly said invest in an NFT is as simple as investing in crypto. Just make sure you research on the project and buy it when it is low and sell high. You are never in debt when you sell high. Just like crypto you only loose money when you see low.

Go to account page and set up your account by updating your profile After you have set up your account click on Create.

I think i should also be emphasised that without a wallet you can’t actually create a page with opensea or the market places. The wallet is like your security haven for your nft collection and you need it every step of the way.
