# 📉💰 Bitcoin Price Drop Alert Workflow This automated workflow checks the current Bitcoin price and sends an email alert if it drops by 5% or more compared to the last recorded value. It’s split into 3 easy-to-understand sections: --- ## 🔎 Section 1: Fetch the Current Bitcoin Price 🧩 Nodes: 1. ⚡ Manual Trigger 2. 🌐 Fetch Bitcoin Price 3. 🧱 Extract Price ### 🧠 What Happens: * ⚡ Manual Trigger This starts the process manually. Think of it like pressing a "Start" button. * 🌐 Fetch Bitcoin Price Uses the Bright Data API to scrape the live Bitcoin price from a specific website using a POST request. * 🧱 Extract Price Extracts the exact price value from the scraped HTML using selectors (like CSS paths). ### 💡 Why It’s Useful: You can track the real-time price of Bitcoin straight from any public site, even those not offering official APIs. It's like building your own live feed. --- ## 📊 Section 2: Calculate and Compare with Historical Price 🧩 Nodes: 4\. 🔄 Convert Type 5\. 📗 Get Last Recorded Price (Google Sheet) 6\. 📉 Find Drop Percentage ### 🧠 What Happens: * 🔄 Convert Type Converts the price from a text format to a number so we can calculate with it. * 📗 Get Last Recorded Price Pulls the previous Bitcoin price from a Google Sheet (a record from last check).
