May be not yet. Bitcoin has emerged as new virtual currency and its just been a decade or so. USD is physical and running since ages. So people love bitcoin but I don't think it is in the place of everybody's mind.
Bitcoin will replace usd but not in this decade or even the next decade. There are many things to do to improve Bitcoin and the technology inside
in fact bitcoin has to solve so many issues, before replacing USD. although it is looking impossible, but to me it can happen in far future, depending on the interest of the people and the new generation interest is already changing toward online business and therefore there are more chances that bitcoin will replace dollar but it will really take a lot of time and before that bitcoin really have to solve so many problems.
The us dollar is tied to the economy of the development at the moment of the state. Tied to bitcoin besides the demand,
I do not quite understand. So I very much doubt that bitcoin will ever win a dollar. Many people are misled by the price of bitcoin, but if you pay attention to Antiques or jewelry where the price even higher and this does not supplant the dollar with the market.
"I don't understand, therefore, the project will fail." Such logic, much wow.
Tied to bitcoin are the people that supports it. The fiat money is tied only with the government which we all hate. Fiat money isn't backed by gold anymore. Fiat money is just.. paper. Bitcoin, on the other hand, is how money should be. What's backing bitcoin is its secure network, the people behind it, and the fact that it removes the third party aka the government from the scene.
Antiques and jewelry are far different from the topic. They are not being traded like a currency because it's hard to do so unlike bitcoins that can be a currency and can be used on other things as well.
