How could such rapid price growth not to be a bubble, I have high confidence the bubble pop and we will see under 200 this month
A bubble is "trade in high volumes at prices that are considerably at variance with intrinsic values." You can have extremely high price growth without being a bubble as long as the price does not greatly exceed its intrinsic value.
The problem is that it's hard to estimate the intrinsic value because it's hard to predict what will happen in the future. Will some governments adopt bitcoin as their national currency? Will some governments outlaw it? Will the media give more negative or positive coverage? What happens when Mt.Gox gets shut down? Will the media start ignoring bitcoin altogether, causing people to lose interest?
For those who believe that bitcoin will certainly fail, it's in a bubble at any non-zero price. For those who believe it might become the global store or wealth, then it can appreciate by 100X overnight and still not be in a bubble. For example, if a block or Arab or African nations announced tomorrow that they are all adopting Bitcoin as their national currency, much as the European nations adopted the Euro, the price could go to $100,000 overnight, and it would not be a bubble.
So asking if it's in a bubble is really a meaningless question. You want to be asking where the speculative traders are likely to take the price in the short term.
I see two possibilities. We're currently experiencing the second highest level of Google interest ever, at about 70% of the April interest. Increased interest means an influx of new investors. Second Market has made it much easier for big players to invest (Rich people don't have to invest time learning about wallets, etc.), so some of these investors might invest large sums of money. There might be a huge demand in China. All of these things could drive things much higher very quickly.
On the other hand, it takes time for investors to become comfortable with higher prices. After the price goes way up way fast, people get nervous, and bitcoin usually has a flash crash, then settles somewhat lower than the peak. As a general rule, the faster the run up, the deeper the crash, and the longer it needs to settle before running up again.
The fact that the recent crash didn't go down far suggests to me that we are probably in for a continuation of the run up. Perhaps starting this evening when China wakes up, or perhaps Tuesday, after the banks wake up after the U.S. banking holiday.
So it could go either way. The best bet is to buy and hold.
