I don't think "soon" but I do think after 15 years or so it is a definite possibility. "soon" i guess is a relative term.
I agree. Dollar is not that easy to be replaced by bitcoin. Because as we know bitcoin is not legalized like dollar. We can also observed that there are some characteristic that bitcoin doesnt have compared to dollar. Maybe after many years it is possible because there are any changes that may happen to bitcoin but soon i dont think its easy as what other thinking.
