To get NFT by bidding in an auction, you need to upgrade your PlayMiner Rank to "Auctioneer" or a higher Tier.
And, you need to deposit an amount of DEAPcoin that is equal to or greater than the bid amount into your wallet.
"Auctioneer" can purchase NFT listed by the OFFICIAL STORE.
"Connoisseur" can also purchase NFTs listed by other members.
