What's an NFT?

NFT, non-fungible token is a record on a blockchain that is associated with a particular digital or physical asset. The ownership of an NFT is recorded in the blockchain and can be transferred by the owner, allowing NFTs to be sold and traded. NFTs can be created by anybody, and require few or no coding skills to create. NFTs typically contain references to digital files such as photos, videos, and audio. Because NFTs are uniquely identifiable assets, they differ from cryptocurrencies, which are fungible.

I already made a TikTok video about the subject: https://www.tiktok.com/@crypto_master_lb/video/7043635784376683777?is_from_webapp=1&sender_device=pc&web_id=7137354890149414405

Example: A house is a nonfungible asset because each house is different, the land it's built on, and its age, you won't find identical houses built exactly in the same location you can tell them apart with different addresses... A $100 bill is a fungible asset because all $100 bills are equally worth the same.

All Bitcoins are fungible which means there is no intrinsic value difference value between all of them.

Pieces of art in general are usually non Fungible because each of them is unique.
