To own an NFT, you have to either mint it or purchase it from another person. When you mint an NFT, you are creating that NFT on the blockchain and assuming its ownership. The NFT is created on the blockchain as a new token and can be sold or transferred to a new owner. Be mindful that minting usually requires gas fees to cover the cost of processing and verifying the transaction on the blockchain, and that this gas fee varies depending on the blockchain you’re using.
After you’ve successfully minted your NFT, you can now sell it on a secondary market. You can either sell your NFT at a set price or sell it in an auction. If you choose to sell your NFT in an auction, you will need to set a reserve price, which is the minimum price that you are willing to accept through the auction. All bids then have to meet or exceed this minimum amount.
