The masses? I suspect banks. Hopefully something like eCash but who knows. We are a long way from mass adoption using bitcoin as a medium of exchange. It will happen. Hopefully it becomes easier as we go.

But the masses do not care about privacy or sovereignty. I do and as long as I can do that I'm happy. I'm not gonna make people care about it. I have tried for decades. The best way though is to show the way. To do more than talk.
