    This error usually occurs when you're trying to access a property of an object that is undefined. To fix this error in cryptocurrency trading, you can check if the object is defined before accessing its properties. You can use conditional statements like 'if' or 'ternary operators' to handle this error. For example, you can use 'if (object && object.key)' to check if the object and its key property are defined before accessing it. This will prevent the error from occurring.

    Hey there! Looks like you're facing an error in cryptocurrency trading. Don't worry, it's a common issue. This error usually occurs when you're trying to access a property of an object that doesn't exist. To fix it, you can use some error handling techniques like try-catch blocks. Wrap the code that might cause this error in a try block, and catch the error to handle it gracefully. You can also use console.log statements to debug and identify the exact line of code causing the error. Happy trading!
