I'm also one of those who can't wait for zerocash.
I expect massive adoption by sites like silk road 2.0 and such. I expect several states declaring it illegal. And of course I expect its value to heavily rise in the middle of war with governments and other negative-hype-raising events.

In the video Dr. Green urged everyone to be cautious about the adoption of the currency -- there's one pitfall if I understand correctly, and that is that since everything is obscured (even the generation of new coins via block subsidy), you can't observe actual inflation in the currency (just try to predict it based on the programming of the source code). That is, if there were a bug and someone were to generate 2 billion coins (as what
happened with Bitcoin), there's no real way to observe that.
