According to online reports, Xiao Feng, founder of HashKey Group, said in an interview with Caixin.com that in the digital economy era, the US dollar stablecoin is actually the tokenization of the US dollar, with the purpose of continuing to maintain and promote the dominant position of the US dollar. This strategy is combined with the tokenization of US debt, making cryptocurrency a "receiver" of US debt. The current attitude of the United States is that if it is inevitable for payment clearing and settlement to bypass SWIFT (International Fund Clearing System), then at least not let it bypass the US dollar; if dollar tokenization is inevitable, then at least ensure that every dollar token is created based on US assets.
