I have published NFTs for sale in:
What is not an NFT
NFT stands for Non Fungible Token
Question: are there Fungible Tokens?
Here is a response by example:
If I lend you a £10 bill, you can return a different £10 bill and I will be happy. Or you can return 2 £5 bills and I will be equally happy. A £10 bill is a fungible token.
If I lend you my bicycle, you can return a different bicycle and I will be very unhappy. Or you can return the same bicycle complete but broken in several parts and I will be extremely unhappy. A bicycle is a non fungible token.
