Mastercard collaborates with MoonPay to launch a global stablecoin card, supporting cryptocurrency payments at over 150 million merchants worldwide. Crypto wallets will soon be able to issue virtual Mastercard, allowing users to spend stablecoins like USDC wherever Mastercard is accepted. This move is part of Mastercard's efforts to simplify digital asset transactions and expand its cryptocurrency influence amid increasing competition with Visa, as stablecoins are sure to become mainstream.
