Acquiring GAME Credits can be done in many ways. GAME Credits is currently available on both CEXs (centralized exchanges) and DEXs (decentralized exchanges). There are benefits and disadvantages to each.
*NOTE FOR GENESIS WORLDS MINING CLAIMS SALE*
If you wish to use $GAME for purchasing Genesis Worlds Mining Claims, you need to either purchase on or move it to a Layer 2 solution so it is available in your MetaMask Wallet on the MATIC (Polygon) Network. You can buy GAME Credits directly on Polygon at Quickswap or buy GAME Credits on Bittrex, BitBay, or Uniswap, and then deposit them onto Polygon using the Polygon wallet.
If you already have GAME Credits on Ethereum, deposit them onto Polygon using the Polygon Wallet to use them on the Genesis Worlds site. Depositing GAME to Polygon lets you use Polygon transactions, which cost less than a fraction of a cent per transaction.
And, when you deposit GAME onto Polygon, the GAME Credits Matic faucet will automatically make sure you have enough Matic to pay the gas fees of your first few transactions, so you won't even have to worry about gas.
Centralized exchanges will require you to create an account. They may also require you to provide some of your personal information in regards to KYC/AML laws. When creating your account we recommend you set a very strong password and always use 2fa/mfa when it is provided to you as an option.
Layer 2 DEXs operate on a sidechain of Ethereum. Quickswap functions on the Polygon (formerly known as Matic) network. They operate the same way Layer 1 DEXs but provide even faster transaction times and lower transaction fees.
