If you already own an NFT, it can only be sold on one platform at a time.
If you are an NFT artist looking to sell your NFTs, we strongly suggest selling your NFTs on a single platform. If you’re minting your art on multiple platforms at different prices, collectors will find out and your reputation will take a hit.
With that said, we encourage experimentation. Offer different NFTs on different marketplaces and services, and see which is best for your or your community.
Be mindful that much of the value of an NFT comes from its scarcity. Yes, you could perhaps sell 100 pieces of one NFT artwork – but would it be a better strategy in the long-term to only sell 10?
