The cryptocurrency card boom has driven monthly transaction volume to $600 million, with USDC closing in on USDT. • Monthly transaction volume for crypto cards reached $600 million in March, more than tripling from $187 million in the same month last year. • USDT has remained the dominant payment currency throughout this growth period, consistently accounting for the majority of crypto card transaction volume. • However, USDT’s market share has gradually declined, while USDC has steadily gained ground, driven by its adoption in Western markets where regulatory clarity and institutional backing are increasingly valued by both issuers and users.
