For me paper money will not disappear, because of small business we have in our sorroundings such as sari-sari store, Carenderia, fare and others that serve as payment. If that will happen maybe for a very very long period of time, that everything can connect totally to the system.
Paper money will be too hard to be washed out in any estate especially here in our country. Not all countrymen are well educated and knowledgeable enough with the digital world. Not even all has credit cards which means it will be very difficult to implement a zero paper money society. With regards to using bitcoin as mode of payment, strong internet connection must be provided and wide campaign about bitcoin must be done.
