Can free NFTs still make you money? I don't bother to claim free NFTs anymore because I have many that has no good use and value,
I think you are too late already, the people who benefited from free NFT's are the first set of people who got them when there was still a lot of hype about the NFT project, not people who are still seeking free NFT's at this time. Free things at this time will get you nothing, especially when it is a free NFT shared to many people.
The NFT trend is indeed declining, but several times I joined the airdrops and once got $ 20, maybe small but we must be realistic because of free NFT and not many things we do, only join in social media, telegrams, discords and so on.
