I know lot of peoples don't even know the abbreviation of NFT. It stands for Non fungible Token. Now let me explain it. In crypto whenever a transaction happens mean you trade your token/coin with other token/coin , all the network record that transaction and this give that transaction a value. Now what if you transfer your token from one side and on the other side you buy a Picture/video any digital form and the whole network record that you purchase that thing with crypto currency, this will put value to that very digital thing and now it called NFT now.
