We cannot generalize ideas or opinions, the dollar may lose influence, even leave a few "cents" with different Fiat pairs, but it does not lose dominance, it is ridiculous to generalize that.
On the other hand, the reference of whoever says it is undoubtedly more than obvious to be against, if there is a movement against that hegemonic dominance that the dollar has, but to mean that it decreases, in the very adjective of that word is like meaning, "I'm afraid," is not meSPAM BANble.
That is to say, we cannot move at the level of sensations, and even less from Russia.
