I'm new in Web3 and I want to be specialized in NFTS I would like to know what are the types of NFTS smart contracts, I read that there are different types of courses based on each concept "Presale" Airdrop" "Marketplace". I just felt overwhelmed by all these types.
I would like to know what are all these types that exist in the market?
How can I understand deeply these concepts?
Thank you
