What It Means When Crypto Cards Convert USDT to USD Instantly
Instant conversion does not mean blockchain-to-bank transfer in real time. Instead, it refers to internal liquidity settlement at the moment of purchase.
Core Concept

- The card issuer controls conversion execution

The merchant never interacts with crypto. They receive fiat.
