Observing the subtle changes in China's cryptocurrency market reveals some interesting signals. While maintaining a seemingly strict regulatory stance on the surface, China's dual strategy of quietly opening new pathways through Hong Kong stands out.

Looking back at how China has defined its relationship with cryptocurrencies, the mining boom began in 2013 when Bitcoin attracted nationwide media attention. Since then, China has been the center of the crypto industry for over a decade. It once controlled 60-75% of Bitcoin mining, and several major exchanges were established in China to lead the global market. However, everything changed rapidly starting with ICO regulations in 2017 and the complete ban on mining and trading in 2021.

The joint statement in September 2021 was decisive. Authoritative regulatory agencies, including the People's Bank of China, officially banned all cryptocurrency transactions. As a result, miners and exchanges moved their operations to Kazakhstan, Russia, and other countries, significantly reducing China's direct influence.

What’s interesting is the recent movement. As the U.S. strengthened stablecoin regulations through the GENIUS Act in July 2025, solidifying the dollar-based payment system, China is responding with a different strategy. Emphasizing the development of the digital yuan while strategically allowing the growth of the cryptocurrency ecosystem in Hong Kong.

The key event was the Hong Kong Monetary Authority implementing the stablecoin ordinance in August 2025. This is not just a regional policy but seems to serve as a 'controlled laboratory' designed by the central government. By testing the possibilities of stablecoins, cross-border payments, and digital asset integration through Hong Kong, China maintains its strict ban on the mainland while exploring these innovations.

Some analysts call this a 'sandbox model.' It means Chinese authorities are observing regulatory operations, compliance issues, and market dynamics in Hong Kong to prepare future policies. Ultimately, the scenario of China opening up to cryptocurrencies is already being mapped out.

The issue of seized assets from the still-ongoing plustoken scam is also intriguing. On-chain analysis shows that about $2.2 billion worth of Bitcoin and Ethereum continued to move actively in 2024, indicating that Chinese authorities are not simply discarding crypto assets but managing them strategically.

In conclusion, China's cryptocurrency opening has already begun. It’s just not happening in a straightforward manner. While strict regulations on the mainland coexist with innovative regulatory frameworks in Hong Kong, China is responding to U.S. dollar dominance in finance. Future policy shifts will likely depend on balancing government control, economic interests, and global competition. As the internationalization of the yuan and the role of central bank digital currencies grow, mainland China's crypto policies are also expected to gradually evolve.
