IS this possible to make bitcoin mastercard.
Mastercard is very helpfull for giving payment.
We can carry it in anywhere.
Is this possible world wide it will show his power.
ITS JUST MY OPINION.
Bringing phone with app installed is much more easy than having card. And if it happens it will be similar to fiat, so what is the use of crypto being digital if we transfor it? We need to think about what is really the main goal of cryptocurrency for everyone to fulfill it with satisfaction.
