Many are asking what NFT is and how we can earn from it. With my limited knowledge, I will try to explain in a layman language. Would love to have comments for corrections or improvements.
NFT is a non-fungible token, which you may have heard of. In other words it a piece of non-interchangeable data stored in blockchain associated with digital file. An example of it could be Pictures, Audios or video. One can create NTF art or a video and host it with any reliable NTF platform.
Making money with NFT could be selling copies or art, music or a clip. Even on can sell the ownership of it. However; they will remain the author of that NFT.
How to create a NFT - You can find any marketplace and mint your asset on one of these NFT marketplace. Few of them to name are Opensea, Rerible, Niftygateway and many others.
