I believe bitcoin will reach the level of what paper money has achieved with financial system and also it will influence online payment system. Paper money already in struggle for it's survival. Bitcoin will boost the extinction of paper money.
Dude He mean to say that bitcoin is superior than paper money So I would agree with him and even I am believing that bitcoin is having that much potential then in future bitcoin is the first costliest stock in some years.
Bitcoin is definitely better then paper money but its hard to believe that it can ever replace paper money or make it disappear as fiat is widely used and accepted and it also holds maximum number of satisfied users.
