I actually made a bunch of NFT's and threw them up on OpenSea before I understood what gas fees were and basically wasted a bunch of ETH/Money. They are all still up there for sale, but as far as I know, known of them have even been looked at.

The other NFTs I deal with are the cards I have from Gods Unchained. But I can buy and sell them through the Immutable X market place, so it is worth it most of the time to put in a little bit of time for them.
