The launching of master card for bitcoin is a good development. It will increase the value and credibility of the all cryptocurrencies and Bit coin. There was already heard about the news of withdrawal of cryptocurrency through ATM,. But Master card is the great development and a good news for all the community that works on online based business. I think this will increase the spread & flow in the future may be a legal or not but people love to do this business. This trade is popular among all communities  and all age of life.
