How does a referral work on Coinbase?

Could you please elaborate on the referral system employed by Coinbase? I'm curious to understand how it functions and the benefits it offers to both the referrer and the referred party. Does the referrer receive a reward for successfully referring someone to Coinbase? What are the steps involved in the referral process? Additionally, are there any limitations or restrictions to the referral program that I should be aware of? I'm interested in utilizing this feature to potentially expand my network and earn some incentives, so a thorough explanation would be greatly appreciated.
