Very likely, especially now that direct transactions using paper money continues to decrease, paper money becomes a crime factor that is robbery, if there is no paper money of course can reduce the robbery in banks or to people so I am sure that no more than 100 years paper money will disappear.
This might be a bit long. this great revolution certainly needs preparation and not necessarily all countries of the world agree that the transaction is changed to be electronic or online
i certainly believe you have a point my friend, since changing ones currency and it is most likely called mass adoption of electronic payments and other online transactions, i guess there might be a conflict as for example i don't think the banks and government will agree directly about that idea and proposal.
