That's true. What scares me is what will happen when those who bought at $80ish to $100ish are going to cash out at $160 to $200. As I said earlier, the feeling is not any more "buy and hold" (which lead to parabolic growth), people is much more cautious now.
The fact that people are more cautious now actually prevents a big crash from happening. Overconfidence leads to big crashes.
