I would say we still use cash pretty often since many establishments only accept that or credit. We do spend a lot via credit card though. Our monthly groceries are paid for entirely on credit. We don't get charged interest anyway so the only thing we need to worry about is having to pay on time and paying the annual membership fee.
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.
Crypto in cash form means you accumulate your funds in crypto and then just have them converted to fiat if that's what the loaner needs right?
