{ "alerts": [ { "coin": "bitcoin", "symbol": "btc", "condition": "below", "price": 85000, "message": "BTC dropped below $85K!" }, { "coin": "bitcoin", "symbol": "btc", "condition": "above", "price": 100000, "message": "BTC crossed $100K! 🚀" }, { "coin": "ethereum", "symbol": "eth", "condition": "below", "price": 3000, "message": "ETH below $3K" }, { "coin": "solana", "symbol": "sol", "condition": "above", "price": 200, "message": "SOL above $200!" } ], "telegram_机器人_令牌": "YOUR_机器人_令牌", "telegram_chat_id": "YOUR_CHAT_ID" }
