I think if the dollar falls, it will affect so much of every currency in the world. Therefore, it is very difficult to fall and its value is extremely stable. In addition, it represents one of the most advanced and powerful countries in the world, so it is supported and a solid foundation.
I agree with your point of view. Usd is a popular currency for the whole world. Certainly it is very stable in all areas. And it is very popular in advanced countries and other countries as well. Therefore, usd will be stable and unchanged, anyway.
It sometimes become volatile. This kind of scenario can be changed. After a long period of time, there will be possibilities that USD will certainly go down. We know how this country control their economic growth, but still, economic inflation affects it own country
