Deep Tide TechFlow News, February 6th, according to Forbes, U.S. Treasury Secretary Janet Yellen recently stated that Hong Kong is currently exploring a new financial system based on digital assets as a "sandbox" for financial innovation. Market concerns focus on potential impacts on Bitcoin and gold pricing systems. Yellen added that there is no conclusive evidence at this time, but related rumors continue to circulate in the market, and the U.S. is closely monitoring the development of the situation. Analysts point out that if a sovereign digital asset system linked to gold emerges in the future, it could have long-term effects on the current U.S. dollar-dominated financial system and the pricing logic of cryptocurrencies. However, currently, most discussions are still at the policy debate and market speculation stage, and the short-term impact on the crypto market remains primarily driven by sentiment and speculative trading.
