Oh, come on. That's just nonsense and proves to me beyond doubt that they really haven't thought this through. The crossover between casual mobile gamers (who presumably they are targeting by putting the games on the app stores) and people who will have any desire at all to sign up to a crypto currency exchange entirely separate to the game they've been playing on their mobile device will be minuscule. Most mobile gamers simply won't be interested in crypto. Not going to happen, I'm sorry.
