I think real money in the future will keep up with the times and technology so that it is more practical, fast and efficient, and it is the same as the nature of crypto currencies and all will be digital
I don't think anything would be exclusively digital even in the future. There will always be the need for something that we can physically touch and hold even with n advanced society's standards. So the digital age may advance and make things easier for us but real money will always be a necessary option.
This seems to be correct, even if more things become digital as time passes there is still a need to have some kind of physical backup in case the technology is not operational at a particular moment in time, so while it is clear we are seeing a transition from physical money to digital money it is going to be impossible to make cash disappear completely.
