NFT allows earning money by playing.
To be specific, they're the NFT games. Because there's this classification of NFTs as plain as it is like the musics, artworks and other NFTs that have been crafted or minted into blockchain to be stored as an NFT.
I think that in 2022 NFT will continue to develop and will bring new opportunities to earn money.
Gaming is a big industry with a lot of users and gamers will be glad to have new opportunities to earn money.
Yes, we might see a bigger development for most of these NFT games and they'll show the sustainability of theirs. But, if the bear market comes, we should see if how many of them are going to survive.
