we can divide alt coins into two parts 1) fungible and 2) non fungible. fungible tokens are this which we buy and trade on many exchange like Eth, matic etc while Non fungible are in the shape of image, gif or video. now its cleared non fungible is also an Altcoins.

We can discuss NFT related discussion in altcoins thread. some thread has been already created in this section for this purpose by Appocollapse and i think there is no need of separate section for nft now.
