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?
There is no relationship between Bitcoin and credit cards. The purpose of credit card is not the same as Bitcoin. From the word itself, credit card is use for debts. The bank will pay your transactions and you will owe them in which you need to pay later. In Bitcoin, you will pay your transactions from the Bitcoin you hold.
