You should be studying what is digital currency first after knowing that virtual currency and digital money are similar to each other and People in your country are not that interested in bitcoin so they can't see the idea of it. It is good that you understand the matter.
Yah I don't find any difference between virtual and Degital currency. When local currency and crypto currencies used online it's said to be degital. But virtual is always used online and it's Degital in nature. As far as I know, no crypto currency has created it's physical notes as of now. It would be really good if it happens. Waiting to feel and experience the physical bitcoin note.
