Dollar is the most used currency in the forex trading, and that is impossible that dollar will be replaced by bitcoin. But only bitcoin will be treated
as the 2nd currency in the world and possibly next to dollar.
I'm not saying that bitcoin will replace dollars, what I'm saying is dollar will always be on the top and bitcoin will be just on the second place.
It depends upon the people who are knowing about bitcoin if they will try to adopt it and if the government of US will going to change their
currency and create a bill for adoption of bitcoin.
Yeah totally, if there are no bill passed for it which is impossible at the first place as government will never allow a currency to be decentralized as there will be no tax then there will be no BTC to replace USD, and it all depends on the users and people to adopt whether they like BTC for their own buying, trading or whatever purposes they have in their mind.
