The dollar being the reserve currency, it is tied up with global inflation, and to slow it down, the central bank has to strengthen the reserve currency. This means higher demand on owning a dollar because people/institutions would want to own a stronger currency to keep them afloat against inflation. With most commodities priced in dollars, this means that other currencies will continue to lose value if global inflation isn’t controlled.
For that reason, there are governments and institutions that wanted to break away from a dollar-dominated market hence they’re considering digital currencies as a viable storage of value. The ability to move blocks of currencies multiple times without central bank interference is not only efficient, it is also best choice if one wants to avoid scrutiny and asset seizure.
