There are a lot of factors which make this situation, so it is not high time to say Bitcoin will replace Dollar soon. Dollar have already made its acceptability and credibility everywhere, people justify or measure every asset with dollar, Every international business is required of dollars. So....
Agree. The Dollar has a well established reputation and trust among its users. It is the reserve currency of the world, and it's widely used among businesses, merchants, and individuals. In addition, the Dollar doesn't have many issues like Bitcoin such as scalability and even privacy.
While the Bitcoin blockchain is fully transparent, that is not the case with the Dollar since it is physical and lacks a chain where anyone could see what you're doing your funds, among other things. With the Dollar, you just pay for stuff without leaving a trace of where it came from. Every Dollar is the same, unlike Bitcoin where it could be known the origin of it, because of its lack for privacy.
Nevertheless, while it may be possible that Bitcoin will never replace the Dollar, I believe that a digital Dollar may be in the works by the US, powered by their own private blockchain. Just my opinion.
