This is not true. The fact that Bitcoin apps have not passed the Apple censor board does not mean that Bitcoin is not mainstream, it does mean, however, that in the process of becoming mainstream Bitcoin may have to take down Apple since Apple's primary business model based upon censorship, control and stifling innovation. The biggest obstacle in the way of Bitcoin is not "the state" or "the banking system" but rather the lockdown of people's computing devices with DRM by companies like Apple.
One simply cannot have truly disruptive innovation in an environment where one has to get permission in order to innovate.
