Paper money is disappearing, thankfully, we do have the technology and capability to create more secure and paperless transactions, also crime would go down in an alarming rate, another type of criminals would rise too but anyways the entire world could be a safer place
Paper money is now not able to cope with the increasing demands of the global village. People need fats transactions and dont like carrying too much cash with them. Robbery rate and murders will also decrease with the increase of digital currencies and plastic money. I dont like paper money anymore because I often am looted by people when carrying cash. Paper money is restricted to poor countries.
