How do I get my free $10 from Coinbase?

Could you please elaborate on the process of obtaining the free $10 from Coinbase? Are there any specific requirements or steps I need to follow in order to claim this offer? Is it a one-time offer or is it available for multiple users? Additionally, how long does it take for the $10 to be credited to my account once I've completed the necessary steps? Lastly, are there any potential pitfalls or hidden fees I should be aware of before proceeding? Thank you for your assistance.
