Mastercard is very helpfull for giving payment.

Is this possible world wide it will show his power.
ITS JUST MY OPINION.
One of the reasons Bitcoin came into existence was to wrest the control of money away from a central authority. Why would you willingly give it back?! This is counter-intuitive.
You're right. The main principle of bitcoin is the decentralization, it is away from an authority. If bitcoin creates mastercard means it breaks the principle. The use of blockchain technology in bitcoin is to offers high transparency and simplicity in the transactions. I think bitcoin should be developed and improved based on the principle.
