i have traveled and lived many countries myself seen things seen life from my perspective the currencies might fall yes but saying that usa dollar will be devalued i can tell you that china yuan is less useless then USD the usa dollar still has big market.
usa dollar is king of the fiat curriencies and btc is king of crypto.
Before the dollar falling there might many other currencies what can fall down first i think so.
i think russian ruble and usa dollars are both very needed since russia got resources what everybody want and usa is just reservecurreny.
Yeah, at least not for now as I mentioned
year by year, I'll just say that since china is the 2nd richest by GDP after US, and look how they managed this pandemic regardless where the virus origins while other including USA are still struggling
China may have the second largest economy but that doesn't mean they are the second richest. The have well over a billion people, you would expect the economy to be big an a pure GDP basis. However, the standard of living or GDP per capita puts them far below many other more advanced economies in Europe and some in Asia, like Japan and Singapore.
