You can earn rewards in the form of cryptocurrency tokens with purchases made using your Coinbase Card. The rewards earned do not expire. However, rewards offered will expire.
When reward offers expire, you’re no longer able to earn that reward. You can choose new rewards every month. Each reward is listed in your Coinbase.com account along with expiration dates.
To choose your reward:
Sign in to your Coinbase.com account or access the Coinbase mobile app.
Select Card from the navigation bar.
Select your reward.
Browser: Select your active reward then choose Choose new reward.
Mobile app: Select Card rewards and choose an available reward.
Select Start earning… to confirm your reward selection.
If your reward offer expires and you don’t choose a new reward, we’ll pick one for you. You can change rewards anytime from your Coinbase account.
