You have done a good work be giving a good definition of NFT, and also differentiating NFTs from other currencies.

Also, NFTs require the use of gas fees to place an NFT in a marketplace. Ethereum remains the biggest blockchain where NFT is been created and this means that listing your NFT, will require the use of eth as a gas fee. The high cost of using eth as a gas fee makes it quite hard for people to list their art.

You have given a good solution to the limit of the development of NFTs, and i believe NFTs will reach a greater height with the solution you provided. Wish you success in this contest
