Pokemon Go has topped all game charts and is the most popular mobile game in all the countries it has been released in so far and caused the stock price of Nintendo to increase to 13%+ in a matter of days which is incredible in itself. However I don't think that Apple or Google will let people buy stuff in the game with Bitcoin because their app stores are a closed ecosystem where people can't use external payment methods and sadly I can't see Bitcoin getting included any time soon if ever. I think only Microsoft have allowed the use of Bitcoin in their Windows store though.
