$USDC I will consider using stablecoins for daily payments. The stablecoin card launched by Mastercard in partnership with MoonPay supports 150 million merchants worldwide, allowing users to directly spend stablecoins like USDC, with transactions automatically converted to fiat currency and no fees. This is very friendly for cross-border payments and fund management. At the same time, stablecoin payments do not require blockchain technology thresholds, and merchants do not need to transform their systems, creating a 'seamless' experience that accelerates the everyday application of cryptocurrencies. Currently, giants like Visa and PayPal have fully laid out their strategies, and the stablecoin market size is expected to exceed $3.7 trillion, indicating that the industry is rapidly evolving towards mainstream payment tools. However, the regulatory framework is not yet fully defined, which may affect the long-term adoption speed.
