I have been using this app #WOMBAT from which one can earn free NFT's and wombucks to convert to crypto.
here is my proof and history of transactions. although they aren't enough if I also want to pay gas fees from same earnings it'll take time. The main thing is that you should be a KYC verified user in order to take out what you've earn. So guy if you play games on phone alot for killing time then this app is best.
Right now I am staking my NFTs on Dungeon master. those NFTs can also be sold out through atomic hub nfts.
