Alright. I bet this is the nth time you see a post like this. I got an offer that is probably not legit but I wanted to use this as an opportunity to finally learn how this works. So please help me and tell me if what I have understood so far is correct.

This person contacted me on Artstation and then asked for my Instagram so we can talk more. To summarize, he said he wanted to give me 3000dollars for each of 6 pieces from my gallery to purchase them as nfts. He said he has a suitable nft marketplace for the transaction and that I have to make an account there. The site he linked is this. https://blumes.store (please do not click on the link if you don't know what it is, I haven't clicked it but I pasted it here so you can see which one it is).

He said I need to make an account there and I need to create an external wallet so he can pay me in crypto.

So then with a quick research. External wallet = crypto wallet I would need to pay something on this site in order to "mint" (create) nfts with my pieces, correct? So that's where a scam would aim, yes?

What I asked him and he hasn't replied yet is "can we do this transaction on a marketplace of my choice?". This should help me understand if this is a scam, correct?

And now please educate me: What is a good site for an external wallet set up? I saw on PayPal that you can link your PayPal with an external wallet. Can you suggest a wallet that has this option? When I have the crypto on my PayPal can I convert it to usd and actually use it/send it to my bank? (PayPal site says that this is possible, does it work with all crypto?)

And finally what is a good marketplace site that I can put my work as nfts in?

I know this is a long post but I would deeply appreciate it if someone can help me understand and guide me here. Thank you in advance.
