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 > Price Alerts
From the Price Alerts screen, you can select to have alerts pushed to your phone or only alert you within the app.
Please note, you will only receive alerts for assets on your watchlist. Alerts will notify you when there are large swings in price over short periods of time.
*Custom price alerts are no longer available.
