What is Coinbase prizeout & how does it work?

Could you elaborate on the concept of Coinbase prizeout? Specifically, how does it function within the platform and what benefits does it offer to users? Is it a form of reward system or something entirely different? Additionally, are there any prerequisites or conditions that need to be met in order to participate in or benefit from Coinbase prizeout? Understanding the mechanics of this feature would greatly enhance my knowledge of Coinbase's offerings.
