If you truly believe that China will become the new America, then you are contradicting yourself by your adherence to the dollar and your continued belief in its efficiency. China cannot take the place of the United States and at the same time remain dependent on the dollar. Currently, there is a complete global trend to get rid of the influence of the dollar, especially on major economies. If many of the major economic countries were not afraid of the agression of the United States, they would have abandoned it completely because of the problems accumulating because of it.

Go and buy as many dollars as you want, because there is a high probability of achieving profits in the medium term for you as an individual. But according to the logic of countries' economies, betting on the dollar has become a major risk.

Why not you consider the Bitcoin option? I think it has better opportunities than the dollar at all levels.
