You can set up automatic price alerts through the mobile app to let you know about price movements for a specific cryptocurrency.
How to set up price alerts:
- Go to Settings > Notifications to turn on price alerts
- Once you've turned on price alerts you can go to specific cryptocurrency pages and use the star in the right hand corner to indicate you'd like to have price alerts enabled
Please note, you can only set up custom price alerts for ETH, BTC, and LTC. Currently, Coinbase only supports price alerts on mobile.
