According to reports from Wu, Jack Zhang, co-founder and CEO of Airwallex, questioned the actual use of stablecoins. He pointed out that even if the price of stablecoins is stable, if the recipient requests settlement in local currency, the costs are higher than those of traditional banking foreign exchange markets. Jack also stated that he hasn't seen any practical use cases for cryptocurrencies in 15 years and believes that issuing currency is the responsibility of central banks, with stablecoins merely serving as financial speculation tools.
