i think that nothing is impossible. The problem is only time, and time here will be counted as a millennium or more and I do not think we'll be alive to see that happen. But now I can be for sure that in the near future, bitcoin will replace the dollar because eventually everyone will use bitcoin.
Ya I think the same as you think. What you are thinking will happen in near future. Since the price value of bitcoin is equal to the dollar. So you can see this will happen in near future. Dollar value may reduce due to the economy change. But bitcoin value will not charge at any time.
