The NFTs come in vast variety, and many ways to mint the one are out there, but the purpose is not clear. Maybe stacking up or holding but they are worthless for their inchoate uselessness. There is never a buyer for my galxe OATs, nor there is dinky beans of value in newly minted NFTs that some new arbitrum projects encourage you to mint. I would direct my diarrhea on NFT and any hawkers mentioning them.
