While the Lynx wallet is a very easy and cheap way to create EOS accounts, there is an even more economical way to create EOS accounts. It requires that you already have an account with some EOS in it though. The EOSToolkit.io website has a free tool that will let you create unlimited accounts for just the cost of the minimum amount EOS and RAM that it takes for an EOS account to function.
Log into Scatter with your current account and pull up the EOSToolkit.io website. On their site they have a tool called “Create Account”.
With this tool you can create a new account. First pick a name for your new account and generate public and private keys for the account (you can use the Grey Mass Voter wallet or similar wallet to generate keys). Make sure you save the public and private keys in a safe place. Then you can pick how much EOS staked to CPU and Bandwidth the account will start with. You need a minimum amount for the account to function. You also choose if you want to transfer the staked EOS to the new account or just delegate it for it temporarily. You must purchase a small amount of ram though.
