It is not only MasterCard but there are also other Banks that adopt to blockchains. But with these good news we see, it is still not good enough for another bullrun and we should still be patient on the current market.
Bull run is a result of manipulation by the whales. It cannot happen only with such positive news. That's the reason that we are still seeing low bitcoin prices even though bitcoin is more massively adopted as compare to last year. Bitcoin will pump only when whales will pump it.
