We constantly check the blockchain transactions so we won't miss your purchase. We also recheck the availability and ownership of each NFT before sending out rewards.
You can buy NFTs from the The Greedy Machines collections in your personal account on our NFT marketplace. Just follow the steps below.
Log in to your GMT personal account and open NFT Marketplace section.

You can pay with GMT (ERC-20 and BEP-20) and USDT (ERC-20 and BEP-20). Select the currency you're going to use — prices will also be displayed in it.

Choose NFTs that suits you best and add them to your shopping bag. You can hold up to 10 NFTs at one time. To buy more, buy the NFTs already added to the bag first and then you can add another 10 NFTs.

You'll receive purchased NFTs to the wallet you select here. It could be:
- Ethereum wallet If you don't have one, add it in the GMT Wallets section.
- GMT Virtual wallet You can send NFTs from this wallet to your Ethereum wallet at any time in the GMT Wallets section.

Click "Check out" to go to the purchase page.
Now NFTs from your shopping bag are reserved by you so you've got 1 hour to complete the payment. If you don't, we cancel the reservation when the time is up.
Reservation reminder will appear on the NFT Marketplace and NFT Payment history pages.

Select the network of your wallet address you want to pay from. It's okey if payment network and wallet address differ from the receiving ones.

Log in to the wallet for which you've selected the network in the previous step. Send the exact amount to the wallet, which are indicated on the payment page.

Your NFTs will be stored in your receiving wallet outside of our service and in your personal account in the NFT Game section. Your rewards for owning purchased NFTs will be displayed in the NFT Rewards section.

You can also purchase our NFTs on public marketplaces, but we can't guarantee their authenticity.
You can buy NFTs from The Greedy Machines collections with GoMining tokens (BEP-20 and ERC-20) and USDT (BEP-20 and ERC-20). We will add an option later on to buy NFTs with USDT (TRC-20) and BTC. Stay tuned!
Individual NFTs from The Greedy Machines VOL_2 collection are available for purchase on Binance.
You can sell the NFTs on any public NFT marketplace. We are also developing our own platform so that you can sell our NFTs if you bought them earlier.
You can find your NFTs:
- In your MetaMask, Trust Wallet and any other wallets outside of our service that support ERC-721 tokens
It's okay if the wallet creates two collections for your NFTs, since we have two different smart contracts for NFTs from The Greedy Machines VOL_1 and The Greedy Machines VOL_2 collections.
