I agree that it is still hard for the average Joe to understand Bitcoin and to use Bitcoin. But we cannot imagine what kind of platform may adopt Bitcoin in the future and may mask all the difficulties of Bitcoin from the average user. Eventhough I do not like centralized platforms taking control of the aspects of Bitcoin which were intended to decentralize and give the users full control, it might help Bitcoin get mass adoption. Imagine platforms like Facebook or Google Play Store or Apple App Store adopt Bitcoin as payment option and make it the preferred payment option... this could lead to mass adoption. Or it could be a new platform which doesn't exist today. 8 years is like an eternity in the tech world. I think it is conceivable.
