I dont think so it will be gonna happen...BITCOIN is always be a Bitcoin..and Dollars is always be dollar so for that Question i dont think that Bitcoin qill replace the dollars maybe yes i agree after 100 yrs.?
even at any time not because of the dollar and currency mengunayai important role. bitcoin today is indeed a trend but this trend we do not know will end up until when
