I want to say right away that so far I am very far from the concept of NFT and my knowledge in this is superficial. Decided to mint the NFT icon from RankerDAO and did it with a cheap BSC transaction. Now in Metamask, I have a token and it turns out its decimal value is zero. But that's not the point, but what should I do with it next? For example, how to put it up for sale, or I can put it on an avatar and other possibilities. Please advise what can be done about it. Perhaps intelligibly understandable guides.
It depends on the project and what they actually offer. If there's no additional utility for holding the NFTs, then your best bet would be to look for an NFT marketplace on BSC and list it for sale. I suggest you check the project's discussion channel and ask other holders what their next move is or better thing, contact the project team to know if there would be utilities for the project NFT or possible marketplace listings.
The OP himself should ask this question, is it worth buying his NFT item? If it is just an ordinary NFT art where everybody can do it, then, what he can do is just put it in the marketplace like OpenSea and hope that somebody will make an offer. Don't expect that you will receive a high value offer because it depends on what you are selling. Sometimes if you got lucky, you can make good money out of it but most of them are just lucky stories.
