Opening trading-card packs has become a $2 billion market. New apps are trying to cash in.

The trading-card industry has ballooned into a $2 billion market, and now new apps are shaking up how collectors buy, sell, and open packs, offering digital versions of the thrill. These apps aim to replicate the excitement of ripping open packs, but analysts warn of potential risks due to their "slot-like payoff" nature, which could lead to over-spending. This shift not only changes the way fans engage with their hobby but also raises questions about the balance between entertainment and financial risk in digital collectibles.
