I still can not understand the reason for the rejection of bitcoin but the approval of other cryptocurrencies and Blockchain, the good thing is that this will open the possibilities for other chains to follow the steps of starbucks and allow payments through cryptocurrencies. At this point we can see the interest of Starbucks in Blockchain technology for the purchase in their stores, this would represent a breakthrough in commerce so that users can use their cryptocurrencies to drink coffee or buy a sandwish.
