  Sure, I can help you with that! Building a cryptocurrency price alert system using python3 websockets is a great idea. Here's a step-by-step guide to get you started: 1. First, you'll need to install the 'websockets' library for python3. You can do this by running the command 'pip install websockets' in your terminal. 2. Once you have the library installed, you can start coding. Create a new python file and import the necessary modules, including 'websockets'. 3. Next, you'll need to connect to a cryptocurrency exchange's websocket API. Each exchange has its own API documentation, so make sure to check that out. You'll need to establish a connection to the websocket server and subscribe to the relevant channels. 4. After establishing the connection, you'll start receiving real-time price updates from the exchange. You can then write code to check if the price of the specific cryptocurrency reaches your desired threshold. 5. If the price meets your criteria, you can send yourself an alert using various methods, such as email, SMS, or push notifications. You can use existing libraries or APIs to achieve this. 6. Finally, don't forget error handling and proper logging. It's important to handle any potential errors gracefully and log any important events or alerts. That's it! With these steps, you should be able to build a cryptocurrency price alert system using python3 websockets. Good luck!
