According to online reports, Xiao Feng, chairman of HashKey Group, recently accepted an interview with a reporter from 21st Century Business Report. Xiao Feng believes that stablecoins can improve the availability of financial services in underdeveloped regions. This is also the reason why Africa has the largest user group of U.S. dollar stablecoins. In the field of cross-border payments, the traditional "bank +Swift" approach may be hit by stablecoins. Xiao Feng believes that they should explore new roles and service methods. In addition, regarding the recent mention of stablecoins by the central bank, Xiao Feng believes that this is a positive signal and suggests adopting a step-by-step, hierarchical and regional approach to gradually promote relevant pilots, and Hong Kong can serve as a testing field for the offshore market.
