you wrong is compare, maybe compare dollar paypal , dollar perfectmoney dollar okpay is right placed compare
is comare USD not equal, USD real curency in the world , bitcoin digital curency
I have no idea what you are trying to say but for me I think USD is still better currency in compare to bitcoin as it can be used anywhere to buy anything.
That is why it is not going to become higher than USD. Because it is implemented by the government and controlled by them. That is why bitcoin is just relying on the price of USD for its value. If you are going to ask the government to make bitcoin as their primary currency well that is the time only that bitcoin is going to be on top.
We all know that we have government in every country democracy, anarchy or monarchy they all want their own currency to be on top. It shows how good a country is and proving they are way better than others. Bitcoin have no home or own government so where could it get support but only from free people.
