We are working on Golden Currency project (
https://goldencurrency.money ), where we issue money that is available both in crypto and in cash form. We find the possibility to use crypto money in cash form as one of advantages. We expect that almost everybody anyway uses cash and in such a case the lack of such opportunity limits the potential use of currency. That's why we started the poll to prove it. Would be glad for your votes and comments regarding your view on such an option.
I think there are many shops that provide credit / debit card payments, so if you say cash I use it not often because of the ease of payment and we can save on a card then use it in payment, we are in the digital era. but we do need cash because some stores points sometimes don't accept or have credit card payments.
