One thing's for sure. Paper money will not be banned ever. People have access with virtual money but we know for a fact that not the entire population are participants in such transactions. Most of the population uses paper money as a medium of exchange that's why entirely eliminating the use of it will have a major impact to them and even to people that are using virtual money. If most of the people will not have the capacity to exchange something to buy something, if ever paper money is banned, they will never have the capability to do so. Without them transacting with the virtual money handlers, virtual money will not have value either. It will be useless.
