i think paper money will be decrease the priority for use, cause now transaction not always use paper money we can use the other things for transaction such as credit card, debit card and also bitcoin
In well developed countries people rely on their bank cards or smartphone in order to complete transactions.
I think in the last 2 or 3 years I have paid all my food shopping, gas for my car, dinners in restaurants, and more, all with my bank card.
I have a 50 note always with me just in case I go to a place or store where I can't use my bank card.
This 50 note has been in my physical wallet for more than 5 months now without needing it. That says enough.
