Wu said that he learned that Airwallex, a cross-border payment unicorn, co-founder and CEO Jack Zhang questioned the actual use of stablecoins in a post. He stated that even if the price of stablecoins is stable, if the recipient still requires settlement in local currency (such as EUR), then the exit cost of stablecoins is much higher than that of the traditional interbank foreign exchange market, making it difficult to save on fees. In addition, Jack bluntly said, 'After 15 years, I still haven't seen a practical use case for cryptocurrencies,' and claimed, 'Issuing currency is the responsibility of central banks,' believing that stablecoins are merely financial speculation tools.
