What is the ruling on staking. creating and selling NFTS

Assalamalykum @Mufti_Faraz_Adam

It seems to me that there is nothing worng with NFTS based on this article

How To Make Money With NFTs | Islam And Bitcoin

However, I still want to know if there are any grey areas I should avoid in NFTS as the above article does not give any ideas on whether there is anything we should look for islamically specificially staking
