I dont have any account on paying in the appstore or playstore that is why I only downloading the free version of the application. But if they consider bitcoin in their payment, it would be easy for some of us that do not have an paypal or etc... To buy some applications in fully version. I hope they grant the wish!
It's not that easy as it sounds. The price of the Bitcoin or any other crypto coin needs to be stable first. However, lets put the stability out of the picture. We need to consider the term "Trade". Before the human invented money as a median of trade, people used to trade irrationally. For example, a cow for a bag of rice. Well, Bitcoin will most likely to face a similar trouble here. Maybe Ripple or some other Crypto Currency can be used in appstore or playstore but BTC is too expensive for these.
