For now I still use both, because in the area where I live it is not so supportive for the implementation of the non-cash transaction system, it still takes a long time to achieve non-cash transactions that have to be prepared from the infrastructure to human resources. The use of non-cash transactions in my area is still limited to interbank transactions or with financial applications that are not non-cash crypto currencies.
in developed countries we still difficult to use cash less transaction.they have less system that allowed it.most of their merchants prefer traditional payment ,so they could take their money directly and used to circulate their busineess without any difficulties.traditional ways always survive.
Yes, I still do need cash for my daily necessities. If I want to buy like softdrinks, high chance that I will pay it in cash in the store not a card or something. Cash always comes in handy wherever I go. No other fuss included, unlike when you are using your credit card, might encounter any difficulty along the way.
