Why cards deserve more suspicion than swaps
A card holds a balance. Unlike a swap that exposes you for minutes, a prepaid or virtual card sits on your funds for as long as you keep money on it — and sits behind an issuer, a program manager and a card network, each of which can impose requirements the card brand never mentioned.
That layered structure is why fund-safety dominates the grade in this category. A generous no-KYC limit means little if the issuer can freeze the balance and demand documents to release it, which is a documented pattern rather than a theoretical risk.
