Non-Fungible Tokens (NFTs) has been under the radar for the longest time, other than when cryptokitties jammed the Ethereum network.
The initial impression of NFTs is just a nice to have collectible, but if you look deep enough NFT can actually lead the industry a long way.
But now NFT involves multiple industries, games, social, sports, etc.
The most interesting concept of NFT at the moment is in the gaming industry, all the characters, items, skins, equipments and skills you own in one game can only be used within that game itself.
But I think the most attractive is the NFT(https://t.me/emit_protocol) that can  be Gamified play and bring benefits(Tokens and NFT).
