Do you think that PlayStore for android phones should accept Bitcoin as a payment or AppStore for Iphone? Steam has no problem with Bitcoins, so why shouldn't PlayStore and AppStore use it? It can use BitPay like Steam and most sites that sell something online.
It would be great, but do you think it will happen?
I do not think that they are going to let Bitcoin be a currency at the Playstore or any other store because they not that many people make use of it.
Maybe if it can become more popular in the future they might implement it.
