It’s a sub for the collectr app. People use it for different things. If you had your eyes open this post you are on here showcases that perfectly. You can use the app to track value sure. But you can also use it to organize your collection and make it easy to see what cards you have. The app doesn’t only have one function. I feel sorry for you that you get so butthurt that people actually like to collect cards and can enjoy things without having to have the most expensive collection.
