In my opinion, most of today's society is in desperate need of cash for their daily activities because most of the shops, traditional markets use cash transactions so that if there is no cash it will be very difficult to trade in everyday life therefore not all markets accept digital currency and not everyone knows about this digital currency
digital currency has not been effectively used, especially for countries that have not legalized it, even there are no transactions using cryptocurrency. therefore we still depend on cash to make ends meet
