The Hedge funds are definitely one of the first steps toward mass adoption -but still, I think, very far away from that place. At this point, there's too much chaos for the majority of people to navigate crypto-currencies in general - even if they could be made to understand how to access it. But most people can't even do that. Add in the crazy volatility - including the rampant scamming - and I think you could be looking at a generation before it is truly mass adopted.

Which is, perhaps, a good thing - the longer the delay, the greater the intervening opportunity.
