I have created my own NFT and now I am wondering how to promote it. What platforms and advertising methods work best? Is it worth investing in marketing or is it up to the community to decide?

To promote your NFT, try sharing it on Twitter. NFT promotion works better if you get involved in NFT groups, talk to influencers, and maybe do some giveaways. Also, list your NFT on places like OpenSea or Rarible with good pictures and a clear description. While it’s good to get the community involved, spending a little on ads or teaming up with others can help too.
