People are becoming increasingly accustomed to using bank cards. Now, with the increasing penetration of mobile and P2P payment systems, the necessity to use cash is quickly becoming obsolete.
Which do you think is the relation between bitcoin and credit card? Don't you think the use of credit card works as the same way as bitcoin does?
No, they do not work the same way. In order to use bitcoin, you have to own assets. In order to use credit cards, you only aquire debt, so at the moment of purchase you don't have to own anything.
