As Trump puts it "I want the US dollar to come on top." Trump is pro-American and pro-US Dollar why are some Americans turning their backs on this great country's dollar for this hyped up bitcoin?

It doesn’t have to do with being a pro-whatever, anyone can decide to be investing in whatever they want to invest in, whether they are that or not. That I am investing in Bitcoin doesn’t have anything to do with me being a patriot or not, I am just investing in Bitcoin because I know that I can benefit from it.
And apart from the benefits I can get from investing in Bitcoin as an asset, there are other ways it’s also useful, it makes transactions very easy and also Bitcoin is available to everyone around the world, which means you can use it as payment to anyone no matter where they are.
