Paper money is relevant in the future through bitcoin transaction.
I dont think paper money will be remove in the future as this is
being used already. However, lets admit thats its really helpful
to all bitcoin users.
I think though true digital currency will be more popular in the future but I'm sure it will not be disappearing to make paper money, because paper money will always be needed for offline activities
Yeah you're right. Cryptocurrency would most likely be considered as an option for people aside from fiat. Though obviously paper money is still more needed than any other currencies, with crypto's growth many people would already be aware of it and would start using it because of ita benefits
