Stablecoins are the optimal solution for a major country's fiat currency to truly marketize, commercialize, and internationalize. Stablecoins are rooted in mature blockchain technology and a country's proactive and effective regulatory policies. Currently, the global competition for stablecoins is as significant as the comparison between Deepseek and ChatGPT, or Huawei and Nvidia, with the United States leading the way, crushing the competition step by step. As a Chinese person, I predict that it will be very difficult for a stablecoin based solely on the Hong Kong dollar to make an impact, as its potential is limited to the radius of Hong Kong Island and Kowloon, and a slightly larger area. Stablecoins are an extension of the power of a major country's sovereign currency, and in the face of a new round of global financial revolution, trivial concerns are hardly worth anything; China should not miss this opportunity.
