# Buy back & Burn

In order to make our token value sustainable and avoid substantial inflation, we will implement following methods:

·        Use 60% of our NFT sales to buy back token and lock away from circulation

·        Implement 2% seller tax on DEX and burn all token

·        50% of fee generating from AI tools, NFT minting will be used to buy back and burn

·        Use 50% income gained from Ads will be use to buy back and lock away from circulation

In addition, we change the way NFT farming should be done in the right way:

·        Each NFT will have an expiry period of 3 months from the time of earning the first token. After 3 months users will have to buy new NFTs and burn old NFTs

·        The earning of token will be calculated reasonably, NFT will be fairly priced and a lot of token use cases will be implemented so that users will have numerous ways to spend AFT token in our ecosystem
