Paper money is normal a good pay method but everything is indeed getting more digital and due to that we can say that it will disappear in about 20 years from now without any doubts.
yeah something obsolete will be replaced with something new, more sophisticated, I know that paper money is very easy to use, but the digital money will be easier and will replace it in the future
I agree, thats because bitcoin is better than fiat. For me bitcoin is as worth as gold. Some people is get saturated of using fiat then they convert it into gold or bitcoin. Bitcoin brings so many adavntage for us such no inflation.
