Like elacsaplau I saw bitcoin to be a hugely asymmetrical bet, so much so that I couldn't understand why almost no one else seemed to be seeing the potential or to care. This made me second guess myself, as I'm actually quite risk averse in nature anyway. I wish I had more conviction in my analysis, but in any case bitcoin was and continues to be something I care about beyond making profit from it. Also like elacsaplau, I've been selling off some lately because I'm overweight in it and because the chance of a crash increases the more it rises.
I have no expectation of bitcoin going to zero any time soon though, and I like many of the others who are selling now will be buying back when/if it seems undervalued again.
I wonder is this something to do with the facebook generation only hearing and seeing stuff that agrees with their world view. If bitcoin is indeed groundbreaking there must be some precedent from the past , is it railways or the invention of electricity, however most investors lost their shirt on those even though they turned out to be groundbreaking.
I'm not part of the facebook generation, but I could make the same accusation that people here who aren't getting bitcoin are failing to grasp the usefulness of something outside their world view.
I think you ask a very interesting question about a precedent for this, about something to compare it to. We're living through the computer revolution, it's happening fast and it's changing the world. Look how quickly digital photography surpassed film, look how quickly smart phones became ubiquitous, Have companies ever grown to be some of the biggest in the world as quickly as Google and Facebook have? Is there a precedent for that? I like to consider the possible reasons: 1) software as a product can scale faster than any traditional production line. 2) software can be distributed globally cheaply and quickly. 3) Internet communication means good ideas spread faster than ever, network/viral effects lead to exponential adoption. 4) The internet has made investing more accessible to people who may not have ever done it directly before, globally.
An interesting consequence of this (and I'm not even just talking about bitcoin here) is that if you consider those 4 reasons, we've the potential to have both unprecedented growth (in software related investments) AND unprecedented bubbles, maybe distinctly, or maybe even both at the same time
