I think you're getting a little off topic here. Whatever demand exists for USD there's a ton of sources in the world to supply same said USD that isn't the united states because as we all know it's a world reserve currency... This helps the USA because it makes it possible to print a ton of money and the inflation gets absorbed by all world wide holders of USD instead of just Americans. This keeps inflation way down while they print more money. But even so $1 is worth less and less everyday. Bitcoin has no such problem. It's deflationary. As long as there's a floor to it's demand it will continue to go up in value. Nothing in the past 9 years has disproved this concept.
