I do have to agree that it's rising way too quickly (too much hype/speculation). My guess is that when it break, it will break hard for many people. Not to 1$... Maybe still 2-digits. As opposed to 2011, a lot more investors are in, so it probably won't be as sharp, but once people lose confidence in Bitcoins, it will gradually lower in value with ripples.
It's just plain silly how it grows now. Of course, people want to move in, but I would probably see like 10% per months MAX as a reasonable growth in normal circomstances. Since it started at around 20$, I say that now the fair value, in light of the recent events, would me more like 30~40$. In fact, Cyprus should have only had minimal effect.
This make me think of the telecom and the dot-com bubble in 2000. Remember how Yahoo! stock raised at that time (
