Selling your Dizzy Dinos NFT is possible on any NFT marketplace out there. The biggest NFT marketplace is Opensea. Once you've connected your NFT-compatible wallet to Opensea, you will be able to see your collected NFTs under "my profile". From there, you can list them for sale and hopefully make that profit you were dreaming about.
Never was it so cool to own a digital asset. Dizzy Dinos' holders can take benefit of so much more than just a digital artwork.
