Hopefully, we will get over with the fiat or paper money and convert it into paperless. Technology would take over the world and we will be using one cryptocurrency which is bitcoin that doesnt need any conversion in every country. 10 years is so long that even we can produce new model of phones every month. This can be happen soon.
I predict that another 10 years cryptocurrency will become a digital currency that is commonly used in many countries, where people view cryptocurrency as part of the world currency that is used digitally so that transactions can be done peer to peer and can occur 24 hours a day.
Money transfers between companies or between families of different countries do not need to go through the bank but can use cryptocurrency so it is very simple and very cheap, besides that it can be done anywhere as long as there is internet access.
