The biggest and most un-expected impact that bitcoin has done is to show that fiat money doesn't have to be used at all. It's an amazing and shocking
thing for an average Joe to grasp, and as soon as they accept how that is true, bitcoin will start posing a real threat to today's 1% privileged.
How bigger of an impact can there be, than to realize that everything you believed was a well thought lie ?
Well I wouldn't say that Bitcoin would pose a threat to the 1% privileged. As long as there is a government to back the use of fiat, there will always people willing to accept it and spend it.
We never know, however. Bitcoin could already be under the watchful eye of large-income individuals, and they might be some of the people driving the price increase recently.
The average Joe is shocked, however, I agree with you on that. They seem to have such a hard time believing that such a thing can exist that isn't a depreciating number.
