Browser-Based Crypto Price Alerts
The BTC.PH Price Alerts tool checks live prices every 30 seconds and fires a browser notification the moment any of your target levels are hit — with zero account setup. You can set multiple alerts per coin, choose above or below triggers, and see exactly how far the current price is from each target. Alerts are stored in your browser's localStorage so they persist across page refreshes as long as you have the tab open.
Browser notifications require a one-time permission grant. If you deny notifications, the alert will still trigger a visual highlight in the page — you just won't get a desktop pop-up. To monitor your full portfolio alongside these alerts, visit the Portfolio Watchlist. For a broader view of market sentiment, check the Fear & Greed Index.
