Risk: Moderate

Buying and selling rare trading cards can be a risky side hustle for beginners starting from scratch, especially if they can't afford to lose money. There is a high risk of losing money due to the fluctuating market prices of trading cards, lack of knowledge in assessing card values, and potential for encountering counterfeit items. Beginners might lose money invested in purchasing cards, time spent researching and listing products, energy dealing with customer inquiries, and confidence in their ability to succeed. Startup costs range from purchasing the initial inventory to fees for online platforms or card grading services, which might not pay off if cards do not sell as expected. Many beginners have reported spending money on cards but failing to make a profit, either due to overestimating the value of their inventory or underestimating the effort required to sell effectively. I'd rate the risk a 2 out of 5 because of the significant potential for financial loss and challenges faced by inexperienced sellers.
