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 are certainly cards now and still coming out, that are good for conversion of bitcoin to USD for immediate use... But I would love to see a pure bitcoin credit/debit card, but that would require businesses to accept crypto. I think that's a bit down the road still.
