I agree very much that the essence of the US dollar stable currency is to make the US dollar one of the tools of global clearing and reserve currency. Cryptocurrency should really be the concept of Internet plus, which also fundamentally re establishes an economic system. And the US Treasury has also reached a certain ceiling. To raise the upper limit of the ceiling, one must bypass existing foreign exchange control measures, and blockchain based stablecoins are the best solution, almost none of which. Previously, the Bretton Woods system promised to exchange US dollars for gold, but now stablecoins based on US dollars and US bonds promise to exchange stablecoins for US bonds (mainly TBills).
