First, you must purchase Ethereum (ETH) through an online exchange. We recommend using Coinbase.com. Once you have purchased ETH, you will need to transfer that to your MetaMask wallet. (Install Metamask at metamask.io and create an account) Please note there are limits on the amounts of ETH you can buy and sell based on your account and the platform you’re using to purchase ETH. There are also time delays from when you buy your ETH to when you can transfer it to your wallet to make NFT purchases. Most platforms require you to hold the money in your wallet before you can transfer it to use for purchases.
