I honestly think that the dollar will win again and again because its just way bigger what is already mentioned here plus its that so many people are already depending on it, and not only people but also a lot of company's are.
Not just with the usage, but the ability to access it. If internet shuts down globally, we can't used our bitcoin too since it's digital. There's no alternative way to use it but to wait again for the internet to bring up. That's why dollar and other fiat currency will prevail forever.
however, dollars was make big affect to the most currency.
