I know paper money got some really disadvantages about the duration and they can easily lead to the inflation but paper money is classical and it's can be used in any technology . With the digital money, only hi-tech can apply them into real life. So what about countries that have low-tech? They will use paper money too. So the thing paper money will be replaced by digital money but need a while to make that happen.
Very true. It needs a country which can provide for it being digital.
Every country still have some places where technology havent reached them. Only cities are being upgraded but farms and other who live in rural places takes a lot of time in the road just so they could go to the city.
Paper money wont be taken out easily.
