No I do not believe that the Bitcoin is ever going to replace money because there are to many currencies for that to happen maybe Bitcoin will take over one currency from a certain country.
Even that is hard to believe that it will happen, Bitcoin has to just stay a crypto currency.
Do you really think that the Bitcoin is ever going to replace money that is not happening because Bitcoin has not even been around for that long.
So may countries would not agree with that idea, Bitcoin needs to stay in it's own lane is what I think.
