Tradelines are credit cards or loans that can help you boost your credit score quickly. They only stay on your credit report for a short time, but they can add 10 to 100 points to your score in just a few weeks. By buying a tradeline, you can improve your credit score and be in a better position to buy a house, car, or qualify for loans with better rates and terms. Think of it like a game, where spending a little money on a tradeline can help you win big by saving, earning, or positioning you for more value later on.
