I actually think (it's a long shot, but possible) that in the future app stores themselves will be hosted on blockchain technology. Something similar to the ethereum smart-contract feature. This would open up Apple to having their own crypto. They have the development power and funds to support such a project. But obviously that's a huge undertaking, even for them.
Thanks for posting! Was a good read.
