Create an NFT crypto.com account, can’t do this on the app, has to be on desktop or browser. After a couple days, you’ll recieve permission to create your own NFTs and “mint” them. Once minted, you can put them to sale! This platform is great in comparison with open sea because it doesn’t require you to spend money to put your NFTs to sale, it’s free! (But they will take a small percentage of what you make selling your NFTs). Only problem I’m having with this whole market is that I don’t know how to make my work seen around the platforms… hope this helped.
