If you're looking to cash out your earnings from a referral code, there are a few things you need to keep in mind. First, you'll need to be sure that the site you're using offers cash out options - not all of them do. Secondly, you'll need to check if there are any minimum requirements in place for cashing out - some sites require that you earn a certain amount before you can withdraw your money. Finally, once you've found a site that meets both of those criteria, simply enter your referral code when prompted and follow the instructions on how to cash out.
